Review: Very good. - Quality product.
Review: Gel coat provided good results - I used this white gel coat with wax to repair deep scratches from dock damage on my 23' sailboat . Per the instructions, the gel coat container was shaken well to ensure wax completely mixed with the epoxy. The gel coat epoxy and hardener were then measured and mixed together per the instructions. I sanded and cleaned the damaged area previously and applied the gel coat using a 1/2 inch water color brush. The bright white finish is smooth, hard, and matches the original hull color very well.

## Features

- PROFESSIONAL-GRADE ISO GELCOAT FOR MARINE & COMPOSITES Formulated for durability and long-lasting performance, this marine-grade polyester gelcoat is ideal for cosmetic repairs, hull finishes, mold layups, and exterior composite surfaces on boats, RVs, motorcycles, and other fiberglass projects.
- DESIGNED FOR COSMETIC REPAIRS & CUSTOM COLOR MATCHING White gelcoat can be tinted with compatible gelcoat or polyester colorants to match existing finishes. Add pigments before introducing MEKP catalyst for consistent color results, from light pastel tones to deeper custom shades.
- EASY APPLICATION BY BRUSH, ROLLER, OR SPRAY Thick, non-sag formula delivers excellent coverage and control during application. Offers a workable pot life of approximately 20–25 minutes at 77°F and cures to a surface that sands, buffs, and polishes smoothly to a high-gloss finish.
- SELECT THE CORRECT GELCOAT FOR YOUR APPLICATION Use gelcoat without wax for initial polyester resin layups or mold surfaces. Choose gelcoat with wax for final coats when a tack-free cure is required. If thinning is needed, use styrene only and follow recommended ratios.
- AVAILABLE OPTIONS, SIZES & COVERAGE DETAILS Offered in white, with or without wax depending on application needs. White gelcoat is available in pint, quart and gallon sizes; Includes MEKP catalyst. Approximate coverage: Pint 12.5 sqft, Quart 25 sqft, Gal 100 sqft

## Questions & Answers

**Q: Does this require that you cover it with plastic in order to cure it?**
A: No, the wax “floats” to the surface and promotes curing.  Gelcoat without wax needs to be covered with a thin film like PVA.

**Q: Does this come with hardener?**
A: Yes it does.

**Q: Can you put multiple coats on if you you need to build up an area?**
A: You can but, if you use with wax you would have to sand in between every coat. The easiest way to do multiple coats is to use the no wax gelcoat and do your build up, then your last coat use the gelcoat with wax. This way you don't need to sand every coat.

**Q: I'm looking to refinish a cultured marble counter-top. Is this a hard surfaced coating that will hold up in a sink?**
A: I would doubt that this would hold up in a sink application.  Try the manufacturer.
