Product is made from Acrylic Resin & Polyethelene Copolymers, and is bascially a sealant. Company claims the product will not cause "yellowing".
It does not contain any wax or silicones.
Isn't Gelcoat basically a pourous surface and needs to breathe ? That's what I've been told. Just concerned, that if this product is used, it and may create other issues with the surface ?
Comments ?

Well - as I am not a chemist by trade, but have talked with a lot of people in the (high-performance) marine industry about this, so... My boat is painted over the gel coat then clear-coated over the paint (was done by Mitch Tolan at Mitcher-T in Michgan). He recommended the Race Glaze to me, and after using it - I am happy thus far. I was also told by the creator of Leverage that carnuba is not a good thing to put on Gel, then he went into some technical reasoning and, well - it made sense to me. As I asked around, the replies that I got reinforced what I was told by both of them - polish (wax / carnuba free) is the way to go. So, to clarify and use the proper verbiage - it does seal the finish, but doesn't "close" the pores of the gel preventing it from breathing... yeah, sounds funny, but it is what it is. If you apply a wax with carnuba in it, you need to really stay on top of it (when dealing with pure gel coat), and technically you should strip off any old wax before applying a new coat. The pores in the gel get clogged and thus do not breathe as they should, it also effects the resins and chemicals found in the lay up of a typical fiberglass hull and you get the resulting oxidation.
Again - not sure how all this "works" per se', but I know guys with $30k, $50k, even $80k-plus paint jobs on their boats and none of them use carnuba-based products to wax-them-up.
