panels do not warp from heat. it is the penning of the metal that stretches it. you must stay at a 45 degree angle to the surface. also high pressure is not needed. my big rig only runs at 35 lbs .
My car was soda blasted, cleaned and epoxy primed. I set my windshield with the old sticky seal in (years later) and when I went to take it back out it was a little stuck and I ended up ripping off the primer down to bare metal It doesn't make me feel very comfortable for when I spend thousands on a final paint job
