The front floorpans of my '56 Olds project are the victim of sitting with water/mud in them long enough that they have rotted through in the foot pan in front of the seat and riddled with pinholes in the footboards and bottom of the firewall. The flat floorpans where the biggest problems are, are getting replaced with new sheetmetal, as that area is relatively flat, and I actually found replacement pans made to fit pretty close to the factory profile. My problem is all the little pinholes in the curved areas of the toeboard and firewall. The compound curves are beyond the scope of my metal working equipment and/or ability I'm afraid, so cutting and patching isn't my favorite solution. What are my other options? Leading? Fiberglass? I learned the very basics of leading in Windfield's classes, and laying down fiberglass is pretty straight forward, but I'm not sure how well either/both will hold up and are these good options for an area like this with heat and water around it a lot. No matter what I fix it with, I do plan on coating the metal with Lizard Skin or something of that nature to seal and sound deaden it.
