Default Hail Dents

I don't think the heating of the skin will damage the foam bonded to the aluminum. I have used this technique on aluminum that was bonded to insulating material and it didn't harm the material. The temperature could be reduced some. Remember, we're talking about a small area being heated. It is less than a square inch at a time. In most cases of painted surfaces, usually a polyurethane type paint, I would infrequently get a scorched spot on light colored paint, again, try reducing the heat some.
I don't know exactly why this works, but I think the heat "softens" the material somewhat and the cold shrinks it enough to pull the dent out.
In those painted areas where the dents would not come out with this method, I always used filler material after preparing the surface for it, then lots of sanding and primer before repainting. Good Luck.
