Hey guys i'm looking to re-color my PTR91 (yes i know it's not an H&K shame on me) trigger group and folding stock to a FDE color, but i'm wondering what stuff is good to use for polymer and won't get all sticky when its hot (summers are avg 110 degrees) or when my hands get a little sweaty. I'd love to do a duracoat or similar eventually but i'm looking relatively cheap and fast at the moment.
