    remember it is not heat that warps sheet metal. it is the anchor pattern . the harsher the media the more it peens the metal which stretches the surface. keeping at a 45 degree angle is all important.

    Maybe a little bit safer to use the tiny acrylic/plastic shot, nut shells, or something "softer", Shine? Still, it's thousands of microscopic hammers on the surface with no dolly behind the panel.

    Enjoy the little things in life, and you may look back one day and realize that they were really the BIG things.

    your only trying to fracture the paint , not pit the metal. i use 35 lbs pressure and stay off the panel 2 ft and use very little media. but my rig is much larger. starblast is a very good media. very fine and will recycle about 4 times .
    when blasting concentrate on peeling the edge of the paint back . blast at the edge at an angle not straight down.
    i use type6 acrylic to remove paint .
