thought I'd give an update
Spent some time building a paint booth with all the useful info here.
Started stripping paint, here is what I am finding
top layer comes off really easy with a razor, dark grey under it sands off, factory paint below it is a real pain to wheel/sand off, primer under it is easy.
Just wanted to make sure I was still doing the right thig to take the whole car to metal and not just scrape the crappy top layer.
I also wanted to get opinions on the rear I found patched, there was up to 3/8 filler in areas, is this normal/o.k. to smooth the welds out a little more and re-fill with that much filler or should I be looking at trying to pull out the dips more?
