How hot can sheet metal get before you have to worry about warpage?
I am using a small propane torch and a scraper to remove the factory undercoating on the inside of my bed sides.
It works really well and I am making sure the metal doesn`t get too hot to touch on the front side.
Does anyone see any problems with this?
I have only done a small section and wanted to ask opinions before I go any further.
Thanks, Mike
