bulge in rt front of roof/top
 

I've got this weird bulge in the rt front of my roof/top. I'm the second owner and have had the truck since the mid 70's. I've never damaged the roof, but maybe the prior owner did?

I hadn't really noticed it before, but when you look at it, it's pretty obvious. Anyone else have a weird bulge like this?

That looks to be really old body filler. you can tell by the way the paint bubbled up in that spot before failing. Jim
