I have a splash guard from a 62 vette that needs some love. First, the person who removed it didn’t take time to free the a couple of the mounting screws. Those holes are oblong as if ripped from the car. Secondly, the piece has a 3/8 by 1/4 inch hole in the middle. What is the best way to fix this short of cutting and welding. Can I use lead-free body solder to plug them, then drill for the original screws? Would this be mechanically strong enough? I know the lead solder works better, but won’t hold up to the curing time.
I’ve tried Alvin’s lab metal on other parts to fill dents with limited success. I know it won’t hold up to the needs of the screw holes.
