TotalBoat White and Neutral Gelcoats

Isophthalic White and Neutral Gelcoats create a durable, shiny finish, and are available with & without wax additive.

Gelcoat with wax makes the final gelcoat layer cure to a hard sandable finish, with no wax paper or special tools needed.

Gelcoat without wax additive is ideal if you're laying up a mold for a new boat or a fiberglass part where you're laying down the gelcoat first, then applying more layers of resin and fiberglass on top. In this case, you don't want the gelcoat to cure completely.

Neutral gelcoat is better with coloring agents. White is more opaque with coloring agents.

MEKP is included as the catalyst. To thin, use styrene (sold separately).

Available in Quart and Gallon Kits. Wax additive also available for use with gelcoat without wax.

  • 1 10" wooden stir stick
  • 1 pr. of large latex gloves

The gelcoat you are buying is an Isophthalic NPG gelcoat with or without wax additive.

The gelcoat without wax is used for layups when you want the initial layer of gelcoat to remain tacky to the touch while you're laying reinforcement plies on top in order to create a strong chemical bond in the laminate. If you use unwaxed gelcoat as the finish coating, you must spray PVA (polyvinyl alcohol) over it or use wax paper or some other means to effect a proper cure.

The gelcoat with wax is used for an air dry post-applied application. The wax additive rises to the surface, making a film that creates an air barrier, allowing the final gelcoat layer to cure properly.

IMPORTANT - Do not Apply Gelcoat Directly on TotalFair:

Gelcoat should not be applied directly over TotalBoat TotalFair epoxy fairing compound or the gelcoat will not cure properly. Instead, apply TotalBoat 2-Part Epoxy Primer or TotalBoat TotalProtect Epoxy Barrier Coat Primer over TotalFair, before applying Gelcoat. Primers are sold separately.

MIXING DIRECTIONSs: NOTE: The higher the percentage of catalyst, the faster the gelcoat will dry. Air and surface temperature will also affect the drying of the gelcoat. The colder the air temperature, the higher the percentage of catalyst you should use.

TotalBoat Gelcoat requires MEKP (methyl ethyl ketone peroxide) catalyst to cure. As with all polyester resin, rate and degree of cure are a function of catalyst concentration and of temperature. Resin and work area should be between 70°F and 95°F to ensure satisfactory results.

At 77°F, TotalBoat Gelcoat requires the addition of 2% MEKP catalyst, by volume: 14-16 drops per ounce, or 2 teaspoons per pint, for a working time of 10-15 minutes. The amount of catalyst may be adjusted in small, incremental amounts, either upward or downward, to account for temperature differences (more for cooler temperatures, and less for warmer temperatures). The acceptable amount of MEKP is 1-3%. Do not use more or less catalyst than this or you may get an improper cure, with laminates exhibiting moderate to severe post cure after demolding. Once cured, the gelcoat can be dewaxed, wet sanded, and buffed.

If using a wooden mixing stick, place the stick in the resin before adding catalyst so the wood doesn't absorb the catalyst.

Directions for Wax Additive (sold separately)

Wax additive is a mixture of paraffin and styrene. When adding it to gelcoat, you must also add the MEKP catalyst. Wax additive is added to the gelcoat on the final layer of a wet layup to create a tack-free surface that sands easily before applying the finish coating. Wax additive is not needed when additional layers or gelcoat are applied on top. Add 20 drops of Wax Additive per ounce of TotalBoat Gelcoat Without Wax. Note that in temperatures below 70°F, the paraffin can solidify in the container. Place the container in the sun or in front of a lamp to liquefy. USE CAUTION - WAX ADDITIVE IS FLAMMABLE!

Wax additive is available in 1 oz. and 4 oz. bottles. Refer to the table below for how much wax additive to add to gelcoat without wax. Too much wax additive will result in fish eye and other undesirable results.

Amount of Gelcoat w/o Wax  Wax Additive Required 
1 ounce  20 drops 
1 pint (16 oz.)  1/4 ounce 
1 quart (32 oz.)  1/2 ounce to 1 ounce 
1 gallon  2 ounces to 4 ounces

Be careful - no instructions, limited self life


As others note, no instructions come with this product, figure is out for yourself! Obtain the technical sheet to determine the amount of catalyst to use. It can be thinned with small volume of acetone, but the results are unpredictable. Be aware that the unstated self life of catalyst and resin is < 12 months!! That means you must use it as soon as you get it. If it remains tacky after a reasonable cure period the resin or catalyst are probably no good. This product can be sprayed using a PREVAL bottler sprayer, or it can be spread using a foam roller. Total Barrier product is almost as good as this gel coat for small shallow repairs. Also, if you use the Total Fair product (very good and easy to use!) you must also use a barrier coat before applying gel coat or the gel coat will not cure properly. Jamestown Tech Support can help with getting the right products and can reveal aspects of using all this stuff that otherwise you have to learn the hard and costly way. I would recommend the product with cautions given above.

Product is very easy to use for the DIY'er. Put on two coats, wet sanded and buffed. Look great.

Easy for first timer


I would buy it again if need be. I used the gelcoat with wax and a bit of white tint for my Laser hull. The quart size is overkill, so I'm hunting for new gelcoat scratches to fix. I guesstimates with the catalyst for a one ounce batch, and it seemed to work just fine.

I would and will buy this product again and again


I bought white gelcoat no wax for mold and ah man the price is right but best of all the quality was way! Ether than i expected i have a big project coming up so ima buy a couple of these soon...




Great quality


Great quality product at a reasonable price. I'll be back again to buy more products to finish the scratches on my Basscat.

Very straight forward but difficult


I used this product on a fairly large area - more than a couple of square feet. I had problem mixing the right amount for the job. The temperature is pretty high so I worked in the mornings and evenings late, but it still set up way too fast for me to do a small part of the area. I finally did it with no more than two oz at a time and put only 10 drops in the 2 oz to get a slow enough cure. Use a square 1" wide spatula and stir like crazy, scraping the edges and the bottom.Also was very messy - it sticks to everything especially nitrile gloves. That was a pain, but the job is super fine!

Minor Gelcoat Repairs


Had ding in the gelcoat about half the size of a dime on the aft corner of the hull. Mixed gelcoat pigment with the resin until I had the color correct, then added the catalyst per instructions. The results were easy to work with. Working on a vertical surface, I had no sags. I'm very pleased with th results. The last gelcoat work I did was 45 Year's ago. It didn't go well. This time, it was a much better experience.

Worked for me!


I'm a novice and this worked nicely. I rolled it on and although it is a pain to sand down, I loved working with it. I used this on the bottom of a 13' Boston Whaler because I liked the idea of fresh gel coat vs paint on the bottom. Primarily for it's hard finish and water resistance. I used this in questionably cold temp (ran the heat in the garage) and it setup even in tough conditions (should have finished before winter).
