Need opinions on what to do about rusty floorpan...??

Well I have the carpet out of the Iroc for wire routing and cleaning purposes, and the area behind the driver's side seat is totally rusted and there's even a hole or two. Does anyone know offhand a company that makes a replacement floor pan for this area? My other concern is that the rust extends a bit onto the 2 rear studs for the seat and onto the raised metal under the studs which looks like a ***** to repair. What have others done about this? Well besides getting a stripped car from AZ...lol. Thanks for any advice.

well I had a $hit load of rust in my 91 RS. Leaking T tops... oh well... The non load bearing areas I just sanded and put down fiberglass and resin.... I had one area under the seat post and I welded in a 1/4 inch piece of steel... Still good.... replacement floor halves are 150-200 and up... I was going to replace the pan untill I got those quotes.

Well on mine there's really not much to weld TO - it's that bad. The weird thing is the whole rest of the car is fine - just this one fairly localized area is rusted so bad I could probably stomp my way right through it. I know of a fairly cheap all-purpose welding shop near me so I really just need some metal that would work...but the closest clean metal to weld to is probably ahead of the rear seat studs, which makes life a pain. That is, if I sanded it down there would just be a giant hole! Should I just take this by a decent shop and get their advice?

I just completed a fix with Por-15. The product is easy to use and comes highly recommended in mags, such as CarCraft and so on. A starter kit, which will probably fill your needs, is only about $15 shipped. You'll also probably require their putty and powermesh. My total was $46.95--damn cheap in my estimation. http://www.easycarts.net/ecarts/Perm...ationProducts/

I would drop the car by a metal shop and get their advice and estimate, since we can't see the car. I have a Rustang I'm restoring for my girlfriend with the same problems.

Since we aren't going to enter this into a MCA show or anything I will treat the floor with POR or Corrosles after chipping away some weak metal. Then in the back of our body shop we have piles of old fenders and doors. I will cut sections of this good metal and use autobody sealant to attach this to the floor.

Then I will undercoat the interior floor as well as the floorboard underneath the car. This will give you a stable platform that won't leak or rust further. The interior is covered with carpet and on the exterior floorpan a good quality undercoating made in two or more applications will make this repair almost unnoticeable.

The floor was getting bad in my 85 TA so me and my friend who works in body shop stripped the interior out of the car cut the floor pans completly out and made up new ones ourself and welded them in, and it done an excellent job. the best way to do it is to cut out all rust and replace the floor if you dont rust will always return. I call rust cancer because it usually always comes back.
