Don't know if you saw my reply on the other post.
I saw what you were talking about regarding the tintable epoxy. It's a misprint by saying "Wetsystem". I think what they actually used is Westsystems Epoxy. It's definately tintable.
I've used the stuff and it's goooood! Spendy but really nice. Good luck.......John
