Dykem and a sharp scribe saved me on pitted weldments too.

Man, this is the same deal as when I stopped using my angle grinder for everything and picked up a $20 orbital sander. Same job, way less damage, and I actually finish instead of fixing my own mistakes. The torch bubbles clear because the heat is pinpoint and way hotter than plastic wants, the gun spreads it out so the whole panel warms up together and the paint can relax back down. I run around 400 to 500F on resprayed covers but I keep the gun moving and watch it from a few inches back, if the paint starts to gloss up too fast that's my sign to back off.

Wait, there's a right way to hold those things?
