## Overview

TotalBoat Marine Gelcoat is a premium polyester resin coating designed for boat building, repair, and composite applications. Its marine-grade durability resists water, weather, and chemicals while offering easy customization through dyeing. The non-sagging, high-viscosity formula applies smoothly via brush, roller, or spray and cures to a sandable, polishable high gloss. Available unwaxed for layups or waxed for finishing, it delivers professional-grade coverage and finish quality trusted by boaters and pros alike.

## Description

TotalBoat Gel Coating creates a super smooth, weather-resistant coating on boat hulls, trailers, composite parts and even fiberglass shower repairs, bathtubs, swimming pools and more. This high-quality boat gel coating contains a premium grade ISO NPG polyester resin that is more durable than orthopedic resins, and is preferred in boat construction and as a boat gel repair kit due to increased strength, flexibility and resistance to water, weather and chemicals. Gel coatings are available without wax for use in layups, and with wax for finishing. The 2% MEKP catalyst is the best, but in cooler conditions, it adds up to 3% MEKP. In warmer conditions or for longer working time, add 1% MEKP. The cured gel can be unwaxed, wet sanded and polished for a high gloss protective finish. The wax free gel is used for the initial layer of a layup, but for a cure without pills, mix a paraffin wax additive (sold separately) at a rate of 20 drops per ounce of wax free gel (400g wax free gel = 1/4g wax additive, 950g wax free gel = 1-2 0.2 9 oz of wax additive and 1 liter. wax free gelcoat = 55-4 oz wax additive). TotalBoat Gelcoats can also be dyed to achieve the desired color. For neutral gel coating, add 10% polyester resin or gel dye (12% for yellow, red, purple, light green and orange). For white gel coating, use up to 1% hair coloring agent. Always mix dye into one gel before adding MEKP. If it is dropped, use styrene. If apply to a mold, please use a mold release agent first. Applying over TotalFair TotalBoat epoxy fairing compound, apply TotalBoat 2 Part Epoxy Primer or TotalProtect before applying Gelcoat Boat Paint. Compare to West Marine, FGCI, Fibre Glast, Fiberglass Supply Depot, Polymer Planet, Hi-Bond and Evercoat Gel-Kote Coats. The gel should be part of the boat fiberglass repair kit. All TotalBoat products are designed for boaters by boaters to deliver great value and great results. 100% Made in USA.

Review: What I have to say is, this gel coat comes through every time. I sands great, is out performs any other gel on desertcart. I made the mistake of trying a different brand and got burned. It didn’t sand well, ate up most of my sand paper, even my 40 grit airfile paper gummed up. So don’t be fooled, this is the only gel I’ll ever use again and I’ve been doing boats, gel coat and fiberglass repair for 40 years.
Review: Product should come with wax additives to add if desired

## Questions & Answers

**Q: 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?**
A: the wax in the gel coat allows it to cure. The advantage of no waz is you can come back hours or even the next day and add additional coats.  For a simple repair, I would get with wax.

**Q: Will this product run, or can it be molded to hold the desired shape?**
A: It is a liquid, so you will not be able to mold it.

**Q: Can this gelcoat be tinted with pigments?**
A: Yes, the gelcoat can be tinted with pigments. If you are not matching a white color, you may want to select a neutral gelcoat to tint. Adding pigments to white will create pastel colors.

**Q: can this be sprayed on? And how many square feet does it cover?**
A: It  it can be spray but you'll need a large tip like your numbers four or six probably six Leavy better it's got about 12 to 15 minute jail time.   I think 1 gallon we cover about 400 ft.² And 10 mil thick.

It works great. Just wish they had all their products in the gallon jugs rather than the cans. Much easier to pour without spilling.
