User questions & answers

Question:	can this be sprayed on? And how many square feet does it cover
Answer:	This is a thick lotion like liquid that needs to be applied and worked by hand or machine and then wiped off. Please feel free to give our Solutions Hub a call at (800) 347-5700 to discuss the specifics of your job. Any of our reps will be happy to help you figure out the best process and products with you.
Question:	Can this gelcoat be tinted with pigments
Answer:	Oxidation remover is more of a rubbing compound that cleans deep down to new fiberglass and has enough wax to leave a shine. 'One Step' is also a cleaner but not nearly as aggressive and has more wax. Both are superb, but for different degrees of oxidation.
Question:	I have a jetski with pits in hull,can i just paint this on and apply a couple of coats,after prepping it and what would be best,with or without wax
Answer:	I tried to remove oxidation from the sides of my Cougar fifth wheel trailer with little to no success. I tried to rub it out both by hand and with a power buffer. I am having more success with TR3 but the product I have is old and I have been told the formulation has changed and the new product is not as effective. It is a lot of work regardless of what you use and the end result for me was disappointing.
Question:	Will this product run, or can it be molded to hold the desired shape
Answer:	Hi i bought. A gal of it i have a 38 ft fifth wheel it is 12'6''tall we used about 2/3of it the hole thing is glass ,it was the best i ever used ,easy on easy off ,shines like a cats butt,it workes great !!!!!

TotalBoat ISO/NPG Gelcoat is Stronger, More Flexible, More Durable, and Easy to Apply.

TotalBoat marine-grade ISO/NPG Gelcoats are the choice of pros for many boatbuilding and boat repair applications due to their greater strength, flexibility, and resistance to weather, water, and chemicals than standard orthophthalic polyester gelcoats. Available with and without wax, TotalBoat Gelcoat With Wax cures tack free to a hard, sandable finish perfect for air dry applications, such as coating. Cured gelcoat can be wet sanded, buffed, and polished to a protective, head-turning, high-gloss finish. TotalBoat Gelcoat Without Wax remains tacky. It's commonly used as the initial layer in polyester resin layups. Our premium Gelcoat comes in White and Neutral colors that are compatible with colorants (pigments / tints) for gelcoat and polyester resins. For best results, be sure your gelcoat and your work area are between 70°F and 95°F.

Adjust the Amount of Catalyst from 1-3% to Control the Setup Time in Different Temperature Conditions.

With polyester gelcoat, proper catalyzation is critical for a proper cure. Cool temperatures may require adding a higher percentage of MEKP catalyst than warm conditions. The more catalyst added, the faster the gelcoat cures. Because air and surface temperatures also affect dry times, take care not to over-catalyze or under-catalyze. We recommend a trial batch to determine final catalyst ratio.

Can be Tinted with Pigments Suitable for Gelcoat and Polyester Resins

Adding color to white gelcoat creates lighter, pastel colors. Adding color to neutral gelcoat creates bold, darker colors. TotalBoat White Gelcoat (with wax or without wax) can be tinted by adding up to 1% colorant. TotalBoat Neutral Gelcoat can be tinted by adding up to 10% colorant (up to 12% for red, yellow, purple, orange, and light green).

IMPORTANT: Always mix in colorant before adding MEKP.

Ideal for Coating

TotalBoat Gelcoat With Wax cures to a hard, durable coating that can be wet sanded and buffed to a super high gloss finish. Use on powerboat and yacht hulls, RVs, composite parts, and much more.

Great for Layups

Apply TotalBoat Gelcoat Without Wax to a mold prepared with mold release agent, then apply a fiberglass laminate over the tacky gelcoat. Works great for spray-up or hand layup techniques to create molded fiberglass boats or composite parts.

Compatible with Colorants

TotalBoat Gelcoats can be tinted to achieve a desired color. TIP: When tinting, always mix in coloring agent before adding MEKP.

• Tinting TotalBoat White Gelcoat (with wax or without wax) creates lighter, pastel colors. Add up to 1% polyester resin or gelcoat colorants.
• Tinting TotalBoat Neutral Gelcoat (with or without wax) creates bold or darker colors. Add up to 10% polyester resin or gelcoat colorants (up to 12% for red, yellow, purple, orange, and light green).

Perfect for Cosmetic Repairs

TotalBoat Gelcoat repairs cosmetic damage easily. It can be applied over cured polyester or vinyl ester fairing compounds, then wet sanded and buffed to a high-gloss finish, for a repair that blends in with the surrounding gelcoat. But what if you used an epoxy fairing compound?

Can you apply TotalBoat polyester Gelcoat DIRECTLY over a repair faired with an epoxy-based fairing compound? The answer depends on a few things.

• If the repair area is small, if the damage is cosmetic only (not structural), and with proper surface preparation—yes, TotalBoat Gelcoat can be applied directly over cured epoxy-based fairing compound.

• If the repair area is large, and if the damage compromises structural integrity—the answer is no. In these cases, you would fill the damage with an epoxy-based fairing compound such as TotalBoat TotalFair, allow it to cure, then apply TotalBoat 2-Part Epoxy Primer or TotalBoat TotalProtect Epoxy Barrier Coat Primer over TotalFair, before applying Gelcoat.

It all started simply enough. As boaters, we wanted better stuff for our own boats.

Even our favorite products, the ones we'd come to rely on, had room for improvement. It'd be nice if they could hold up longer, cure faster, coat better, apply easier, and—since we all know boat ownership creates a mini maelstrom in your pocket—cost less. So we took everything we knew from 35 years of customer feedback, combined that with our own boating knowledge, and after a few years of rigorous R&D, TotalBoat was born. Launched, rather. By boaters, for boaters.

Need help? The members of our TotalBoat Tech Team are boat owners who really know their stuff. So whether you're trying to figure out what to buy or the best solution for your particular project, they have years of hands-on training, experience, and a passion to help you succeed.

User questions & answers

Question:	Is it thin enough to use a paint sprayer
Answer:	You need to have a high pressure sprayer. I think A134 gun maybe. You can probably look up gel coat spray gun
Question:	Is this bright white or off white
Answer:	Bright White. a good buffing when cured really brings out shine
Question:	difference between with wax or without wax
Answer:	Gelcoat without wax will not harden if it is exposed to air. The gelcoat with wax will harden exposed to air. The wax rises to the top and makes a skim coat over the top making a separation barrier so air can not come in contact and the gelcoat will cure.
Question:	What is the difference between wax or no wax
Answer:	I believe a difference is that with non-waxed you can apply coat upon coat, and with waxed you must sand between coats.

User questions & answers

Question:	Pardon my ignorance but may I use this after sanding too deep (through the gelcoat)? I mistakenly used a #60 paper. Is this the correct product
Answer:	Yes this product will work great. I was far below the gelcoat and it worked super. Careful to use the proper amount of hardner. Use less harder if concerned.
Question:	How do I match the color
Answer:	Trial and error. Get a pack of popsicle sticks for mixing and a box of clear, small mixing cups with ml markings. Put a fixed amount of white gelcoat in each cup and a varying amount of dye drops in the cups. Mix em all up, apply, and let it sit for a several DAYS in direct sunlight. The mix that best matches the original is the winner.
Question:	How white is this
Answer:	Is this a serious question or are you a racist? It’s white. Project differs shades of light on it and it will reflect different shades of white.
Question:	As with regular fiberglass resin I know the ratio is 10 drops of hardener with every ounce of resin what would be the ratio for mixing this
Answer:	That would depend on how "hot" you mix it (how fast you want it to set up.)

User questions & answers

Question:	Will this work for “below the waterline” on a jet ski
Answer:	It worked for me, It is color pigment in regular glass resin
Question:	I just noticed some cracks in the gelcoat on the left top corner of my camper today. How hard is this to use, and any instructions to share
Answer:	Be advised gelcoat has no tensile strength to speak of. If it is cracked it is usually because the underlying fiberglass is either cracked or insufficiently strong to prevent stress cracks in the gelcoat. They way to check is to use a die grinder (electric or air) and a burr to grind out the crack a bit to investigate. Make a vee shaped bevel along the crack just through the gelcoat to see what the fiberglass looks like. It is also advisable to not ruin the existing shape of your corner because then you will have to remake it. My point is that if you need to repair or reinforce the glass of your camper top, first look to see if you can access the interior and beef up or repair the glass from the inside which won't affect the shape of the outside and won't be seen. You can then just fill the expanded crack in the gelcoat. It will be easy to fair it and retain the original shape of the corner. If the glass is cracked or you want reinforce it, and you cannot access the interior of the fiberglass top, make your bevel wider and deeper. For strength you want at least a 5 to 1 bevel (each side). You then cut glass cloth or mat in strips to fit in the crack. You start with narrow and get wider and wider until the wedge of the bevel will be filled. Don't completely fill the bevel. You need to leave room for the gelcoat so it can be faired with surrounding surface. You will need a bubble roller to roll out each layer the fiberglass. Try to fill it all at once, but if you don't have wax in the resin you can let it kick and put more coats after it kicks completely without grinding anything but high spots. I find it easier for small jobs to fill it completely. I do everything possible to avoid grinding fiberglass. Once it kicks (it will remain tacky due to lack of wax) you can fill it the rest of the way with color matched gelcoat. Again don't use wax until the last coat of gelcoat. The gelcoat should be proud (stick up beyond the surrounding surface so that you can sand it back, fairing it. When it is fair, rub it out with polishing compound not buffing compound to make it shiny and then wax it.
Question:	Is a color chart included with instructions on how you can achieve different colors(blue and tan in my case) by mixing these tubes
Answer:	No color chart is provided with this kit, however, a gelcoat color guide is available on our site. Bottom Paint Store
Question:	Will this work on RV wall where a screw penetrated from inside out
Answer:	I would grind down the protruding portion of the screw first then you could use it to fill in the area

If not mixed properly your gelcoat will have patches that are still sticky. The wax helps dry the gelcoat all the way so it won't be sticky and also so it can be sanded. Remember without the wax your gelcoat will remain sticky.

• 1 Pint covers approximately 12.5 square feet Exceptionally easy patch and repair properties, user friendly application properties
• Good water and blister resistance High strength and hardness and 5.5-6.5 percent elongation in tensile ( i.e. No more cracking)
• High-viscosity has great coverage. Compatible with pigments made specially for polyester resin or gelcoat.

User questions & answers

Question:	Does this come with hardener
Answer:	Yes it does.
Question:	Can it be applied with a roller
Answer:	Yes, it can be applied with a roller.
Question:	Does this require that you cover it with plastic in order to cure it
Answer:	No, the wax “floats” to the surface and promotes curing. Gelcoat without wax needs to be covered with a thin film like PVA.
Question:	I'm looking to refinish a cultured marble counter-top. Is this a hard surfaced coating that will hold up in a sink
Answer:	I would doubt that this would hold up in a sink application. Try the manufacturer.
