I've noticed lots of people starting to do their own bodywork. Lets all put this up and give some tips. I've did all my own work on me 89 CRX Si. here's some pics.

This was a nasty hole in the passenger rear quarter window.



The black on the edges is POR-15 rust stop stuff. Works great too. I left the edges jagged so a fiberglass plug would hold.

I ruffed the inside of the panel with 80 grit sandpaper. I took fiberglass LONG strand woven cloth. This stuff kinda looks like straw. Then take some fiberglass, I used this stuff referred to as Angels hair. It's a green gel with strands in it.

Mix the fiberglass resin and spread onto the cloth. I stuck the matting in from the inside/ out and duck taped cardboard to hold it while curing. After it hardened I knocked it down a little 80 grit and then used body filler to smooth it out.

here's the end result with out trim to cover the high rise though.
