The paint is simply rustoleum grill/barbeque paint. I noticed today, it looks fine after running the truck back an forth to work except for the weld locatioins. At the welds the paint is all bubbled and peeling. I assume one of two causes: 1. I simply did a poor prep job around the welds before painting. or 2. The welds are hotter due to more metal in that area and as a result, is retaining more heat, causing the paint to blister and peel. Hopefuly it's the former; I can reprep and repaint when I eliminate the x-over pipe behind the engine.
