## Questions & Answers

**Q: will this yellow,or chip off?**
A: Since , it's a thin coat that  penetrates the gel coat, it's not a another layer of product sitting on top. No chipping and I have not had any yellowing on the white gel coat sections and on the dark green section  the color comes back every time.

**Q: What are the application requirements and procedures, as per the label or otherwise?**
A: Easy to use just like the label states, just cleaned the surface well and made sure it was dry. Rubber the the product on with a clean lint free rag, the rag will get hard once the product dries so it will be a throw away. But the dash of my 1991 SeaRay looks almost new now!! It had really bad fading dark grey gel coat which was almost white in spots

**Q: Does this do the same thing as poli glow? Makes it look new but puts a coat over the gel coat? That is a pain to get off when spots of it comeoff?**
A: this product is not for water spots its a replacement layer of gelcoat.  I would only purchased for damage finish

**Q: is this product ok to use on the hull of a boat**
A: Yes the hull of the boat is exactly the type of fiberglass surface presto gelcoat Rejuvenator is meant to shine and protect.
