windshield pinch weld pin holes

[MikeP]

87 CRXsi project, The roof right above the windshield was dented, broken windshield. Upon removal of glass and urethane and goop, aside from the dent on the roof that has been banged out and ready for filler, I have about a 6 inch section near the dent where there are pinholes, a few near the top where it will show when done and glass is installed. Is there a real good way to fill those holes? Or do I want to transplant a section of the roof skin including the pinchweld from my donor car? An advantage would be the moon roof would allow a great place to replace to. Thoughts? Thanks, Mike

Sandblast and fill with Brass or Solder. If you are DIYer, then make sure to Neutralize properly.

Really depends on your access to the other side. If you can sandblast both sides you will be fine welding them up.

If not, the other side of the panel will be covered in active rust and will eventually make it's way back through. How I proceeded would depend on the access I had to the other side.

If I had a donor car I'd be cutting out a patch to repair the problem area.

I can get to the other side, at least enough to see that there isn't rust showing on the inside. But I understand that unless ALL of the rust is gone, it will just come back. My plan, I think, is to cut a chunk of the roof out of the donor car, then carefully remove the roof skin from this roof section. This will allow me to finalize where I make my cut on the good car. Then, carefully cut that exact skin section out of the good car. This should be interesting to say the least. Is there a link here with pictures so I can see the best way to do this? Thanks, Mike.

There are a couple of links that can give you a few tips on this procedure but I haven't taken pictures of this exact situation. When we do a patch we almost always use a "backing strip" so the procedures linked below are done using this method.

The Road Runner link shows several different methods used to repair rust damage including the backing strip, using EZ Edge and sectioning.
