wheelman Posted November 29, 2004 Share Posted November 29, 2004 How large is the rust spot? Post some pics so we can get an idea and make suggestions. My car was rusted through in that spot so I got a chunk from a 260 in a local JY to replace it. Turned out very nice but was alot of work. I ended up cutting out the entire battery tray area, part of the firewall and the passenger footwell to get rid of all the rust. Learned to weld with a MIG/wirefeed to do the project. If I were you I'd locate all the rust you can find, cut it out and weld in new steel. I removed most of the undercoating on the bottom as well as the floor in the cabin and also found rust in the seam where the floor and firewall meet in the driver footwell. If you're going to all the work it sounds like you're doing might as well get all the rust the first time. Wheelman Quote Link to comment Share on other sites More sharing options...
Guest 83supaZ Posted December 1, 2004 Share Posted December 1, 2004 its pitted on the firewall... rusted through on passanger wheel well.. and a few smaller rusted through (quarter sized) holes on the frame rail.. pretty big hole maybe after all is cut about the size of a basketball on passanger wheel well... i am thinking about fiberglassing it.. tape cardboard w/packing tape on it to the bottom.. fiberglass mold the top.. then fiberglass it onto the car after all rust is cut out.. i dunno.

SSflyer Posted December 2, 2004 Share Posted December 2, 2004 If you're going to the trouble of fixing it, then patch it with metal. I suspect that a fiberglass patch will rattle loose in no time. I did exactly this same patch and it's not as hard as you would think. Use the piece you cut out as a template and cut the new part just a little bigger. Just don't be in a hurry and work it until it fits. If you have a hole in the frame rail you'll absolutely need to have that fixed. You don't want your car folding up...

wheelman Posted December 2, 2004 Share Posted December 2, 2004 What ssflyer said!!! Sounds to me like you're situation is just like mine was except my frame rails are fine. I did notice that once I had the patch welded in the car jacked up more evenly than it had before. I would use metal to patch the hole not fiberglass.
