It features a wax additive for a tack-free cure, supports custom tinting, and offers a smooth, high-gloss finish that sands and polishes easily.

## Description

White Gelcoat with Wax Pint with 15cc Hardener (MEKP) Gelcoat with wax is for the final coat. The wax settles to the top and need to constantly be mixed. 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.

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

## 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.
