After gutting the 66, I found a few areas in the floor boards that have som pin holes and 1 or two areas above the cross supports that may be 1x1 inch rusted thru, all in all they are very solid. What would be the best way to fix this ? Weld in patches over (if so, what guage metal would you use), fiberglass ?

thanks

I'm no bodywork expert, so I'm just trying to go by what I have seen done on other cars.

1. No Fiberglass. That reminds me of something a used car dealer would do for a quick fix.

2. Cut out all the bad areas. As far a what gauge, I don't know what gauge the floorboards are, so try to get something comparable.

3. I would try my best to butt weld all the pieces in. Once finished and painted it leaves a much cleaner look.

Just my $0.02.:)

It depends on what level repair you want. If your going for a show car, you want to replace all of the weak metal with new by welding. If it's a driver and your looking for a temporary repair (a couple of years), then you can use fiberglass.

For my car, I purchased galvanized sheet metal at Home Depot and screwed it in for patches. My car is going to be a driver, and my plan is to replace the floor panels in a year or 2, but for now it will let me get it inspected.

If your going to patch, with metal or fiberglass, you want to clean the floors and use either Eastwoods Rust Encapsilator or POR-15. Both do the same job.

Good luck. :waving:

You can also use a metal patch panel with some metal adhesive (Fuzor). Not as good as welding, but always an option.

I used 22 guage sheetmetal from Home Depot to do some spot repairs on my floors. There wasn't enough damage to justify replacing the entire floor. I cut out the damage, traced the cutout area onto the new metal by placing it against the backside of the repair, made my patches, and welded them in.

You will need a MIG welder and a piece of brass or copper on the backside of the seam to keep from burning through.
