Well I've gotten alot of people how well high temp powder holds up but I've never been able to give a good answer from personal expierence. Well that will change here soon. I ordered new exhaust for the powerstroked Excursion and powdered it high temp black. I hope to have it on in the next few days so we will see how well it holds up. Here are 2 of the 3 big pieces. I could have never dreamed of doing parts like these in that little oven.
