Shine will the heat gun deal work on stripping an original lacquer finish say on a 50's GM ?
I'm about 90% done with stripping a lacquer job I sprayed 40 years ago. Tried the plastic razor blades but had too much problem with the paint sticking to the blade, so I went back to standard blades. Coulda been just my technique was wrong with the plastic blades.
I started with a $10 HF heat gun that I'd had for years, and it worked okay. Then the gun's switch died, so I got a new gun from the local Ace Hardware for about $40. It has adjustable heat as well as a couple different fan speeds, and the job went twice as fast with the new gun.
One thing I've found that seems to help with the steel blades is to run the edge across a sharpening stone to just slightly dull it and to stone the corners just a bit to soften the dead sharp corners just a bit. The blade is still deadly weapon sharp, but the stoning seems to greatly reduce the tendency to snag and break a piece out of the edge, and it still peels the paint as good as ever.
