Perhaps Chris can explain his "proper prep" work technique. I have taken quite a few parts from the *interior* of the van, stripped then down to bare metal. I then primed with the Krylon primer designed for their paint, did a light sanding then hit with a second coat of primer and finally two nice topcoats, allowing each coat to dry overnight. The paint chips extremely easily, and even a Scotch Brite pad will scuff up the surface. Personally, I think Krylon paint is JUNK. I can't imagine using it for exterior use, unless you just look at it and don't actually use it. I top coated my propane tank after a POR-15 treatment with Rust-olemn High performance enamal "professional grade", and it too chipped. I used FOUR top coats too! I'm sure glad I put the POR-15 underneath it-that stuff doesn't chip. Benny Boy recommended an automotive type of paint, and that's what I would use for anything exterior. As the saying goes, you give the you pay for. A five dollar can of spray paint, gets you a five dollar job. A $300 a gallon automotive paint is going to outperform in every case. Yes, proper preparation is essential in either case. Troy |
