The quarters were from goodmark, they are just the skins not a full quarter. they were really easy to put on, not much fitting. Yeah I brushed the POR 15 on and it comes out with an amazing gloss finish. It came out so well that I put it on my firewall, with a brush. Haha. Well I'll speak for POR and tell you this, I put this on my sub frame as well and accidentally hit it pretty hard with a hammer, and it didn't even scratch! I'm all for it, although it's pretty expensive. But definitely worth it. And thanks for all of the responses!!
