Default Small holes in the front floor pans.. Replace, small metal patches or ?

Unfortunately, water (mixed with mouse urine/feces) sat in my Texas floor tub for too long. I have these small holes isolated to the passenger side front floor pan. The metal around the holes is solid..
The rest of the passenger side floor is clean. Weld in patches? Weld in a new piece? Glass it???

This is the driver's side. Looks like the urea/fecal/ water mix sat in the wire sleeve channel..

Tough call. I guess it depends on how far apart you plan to take your car during the project. I tend to lean towards a full pan replacement from rocker to rocker and toeboard back to rear seat crossmember. For me it's easier than several large patches. If you can do it with just a few small to medium size patches then that might be just as easy. 6 of one, half dozen of the other kinda thing.

I've done it both way and when given the choice, I usually just replace the full section. I always prefer to reuse the original braces if they are in good shape since that provides an excellent chance of things lining back up nice later. A full pan really isn't that hard as long as your rockers and braces are in great shape.

I would never glass anything but that is just me....

Here is where I am at. It's a convertible, 70... It's stripped. I wanted to pull the frame.. However, I've heard most frame off's do not ride as well as leaving the frames on the body.
As far as the floors, these are the only rusty/ rotted sections...
This car is a father/son project that I will pass on to him when the time comes. It's a numbers 4 speed convertible.

I would just do a new floor then. They arent very expensive without the braces. I did a full frame off but was able to change out the floor with the body on the frame still. I prefer to have the body on frame when replacing floors because that way I know everything will fit later.

My son helped me replace the floor in my car. He had fun with the plasma cutter.

If you have more time than money I would weld in patches. Matter of fact that's what I would do, it just requires a little more patience.

I'm dealing with the EXACT same thing, just random pin holes from sitting water. I bought the floor sections in quarters and cut the patches out of those. The surrounding area was WAY too solid and unrusted for me to replace the entire floor and I just plain wanted to keep as much OEM metal still in place as I could.

But ... it depends a lot on your skills and equipment, nice butt welded patches are tedious and difficult on complex stampings like floor boards. I started a thread on the project, which I am still working on http://forums.maxperformanceinc.com/...d.php?t=842662

For me it would either be butt welded patches ... or if you can't do that ... entire floor sections .... no lap welded patches.

Default rust holes

Try using 3M panel bond adhesive. Very strong. Billk

I had a similar situation in my 'bird, driver's side only, and it was a couple small areas.

I ended up using POR-15 epoxy putty, and did kind of like a skim coat. Once full cured, I sanded it, and finished the entire floor with POR-15 paint. Can't even tell where the repair was.

That was in like 1984, still have the car, still can't tell.

You can use any type of long-term epoxy putty/metal filler and you should be fine.

Whoever mentioned that a car never rides right when you do a frame-off obviously has never done it. It's simply not true, it will ride 'right'. You eventually have to change the bushings at some point, no difference really.

Depending on the car and frame type, you may have to support the body 'form' with braces when you take it off the frame, but no big deal.
