## 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.
