    seam sealer, most auto parts stores have it in caulking tubes, at least the ones that carry auto paint.

    I noticed that too..cheaper stuff works just as well!

    I think the 3M "Body Seam Sealer" works OK,but the OEM stuff GM uses caused more rot than it prevented!..the 3M stuff is quite pricey,it was over ten bucks a tube last time I bought some well over 10 years ago..you can get quart cans too,and use a acid flux brush to spread it..

    But I used regular Butyl rubber caulking designed for metal siding and gutters from Home Depot to caulk up the seams on the patches I put on the tail pan area of my 81 G10 van about 5 years ago,and its held up excellent!..better than the 3M stuff if you ask me..and it was only 3 bucks and change for a tube!..you cant tell it from the 3M stuff..it dries hard eventually,but takes quite some time too,whereas the 3M stuff skins over in a few hours..

    Don't use RTV to seal body panels--it will eat the steel eventually,and cause more rust!..I've used roofing cement and asphalt roof patch stuff in tubes to caulk up floor patches too with good results..but beware it may remain sticky,dont use it where your clothes or feet will touch it!..lasts forever though...:crazy:
