I may have done a not-so-smart thing when I sanded down the roof on my car. I used a sanding disk on my grinder tool. This can removal material pretty fast, so I was careful not to use too much pressure. As I was sanding at the middle of the roof, I noticed the roof was getting warm (not glowing or discolored by any means), I heard a hollow "plunk" sound and noticed the roof caved in just slightly. I thought it would come back out when it cooled down, but now it seems I have a permanent deflection here. I wonder if there's an unobtrusive way of trying to get the sheet metal back out like using a hairdryer or a heat gun while I somehow pull it simultaneously. I don't want to go through the hassle of removing the headliner. The deflection is relatively large - maybe 5" diameter, but shallow, maybe 1/16" deep. If there are no Q&D tricks I can use, then I'll probably just use some filler to bring it up flush - I have some Evercoat Rage filler that seems to be pretty good. Hope to hear from some autobody gurus out there!
