## Description

Black Gelcoat with Wax Pint with 15cc Hardener (MEKP) Gelcoat with wax is for the final coat. The wax settles to the top and needs 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: Great stuff, worked great. Instructions were provided for catalyst. Highly recommend.
Review: Excellent Gelcoat for making new things!!! I use wooden moulds, painted and then waxed with Pure Carnauba Wax, then a nice silicon release. Applying the Gelcoat, and shortly afterwards fibreglass, resin, etc - Wait and then new part easily pops right out - beautifully smooth - Have not had a part pop out this good for a long time! Will be buying more shortly! Highly recommended for fibreglass work - if you want superior quality!!

## Questions & Answers

**Q: Using this on Remote control car body in order to make it harder stiff and less resistant to bending at speed will this get hard applied to plastic?**
A: Polyesters will not stick to most plastics.

**Q: Can you apply rubbing compound after sanding this product?**
A: Yes. To get this super smooth and shiny I would recommend wet sanding starting at around 220 or 320 and work your way up to about 1200. Then start with the rubbing compounds. The other way is to use a product called duratec high gloss additive and spray the gelcoat. Then you won’t have to do as much wet sanding.

**Q: Do i need to use a product to make this thicker like paste to fill the holes and cracks?**
A: Yes, you can use cabosil to thicken the gelcoat.

**Q: Is this brushable**
A: Yes this can be brushed. Keep in mind that when brushing it will leave the brush marks. Sometimes its better to roll it on. If you want a nice smooth surface you will have to wet sand and polish afterwards.

Got it for touching up the bottom of my jetski and it worked great. Just what I expected. It can be a little messy to use, but it stayed on great.
