I used Krylon Plasitc fuzion on my gun and it worked great! UNTILLLLL i went to hold it.. the paint is so damn tacky that i dont even even want to touch it. I tried using a heat gun on it to harden the paint but no dice, this was after a day and a half of letting it dry! So pissed as i was i put it in the oven at 200F its lowest setting let it get nice and hot for 10 minutes or so. No luck! I will never use that crap again...
[The gun was a Swiss Arms Sig P260 Clear]
