temporary body work

67 Dart GT

I really don't want to get into the awful job the body shop did. Needless to say they left fiberglass I put in, and it was all supposed to be removed and done correctly (I was 16 and my first time doing body work, so it wasn't great). Car also has way too many different versions of the paint I wanted, and wasn't even the correct one.

This is the worst spot, and it has killed the trunk pan. I need to get the window to stop leaking, the fix only needs to last about a year to two years and I will have it into a better body shop. This is the rear passenger side. My tentative plan for the body is the sand, use naval jelly, bondo, prime, and paint it. For the window seal area, can I use RTV, silicone, or caulking to put in the little valley next to the window gasket? Both the front and back and back window in the lip of the window also has tiny holes I plan on doing the same.

The trunk and hood both have awful clear coat peeling, you can see some of it in the picture. I am thinking of color sanding it, seeing if waxing it after will shine it up. If not has anyone used the spray clear coat or polyurethane?

I haven't done body work in probably 14 years, so I am a little rusty.
