i was under the heep today insatlling an sye and noticed two small rust patches.about the size of the tip of your thumb.now i dont think this constitutes full replacement of the floor pans but i goy to do something. i plaaned on pulling the carpet anyway and herculing it.i know theres a product out there that bond to rust and is almost as hard as steel(which is stronger than the unibody).i've seen it used on a couple old classics that were being restored but cant remamber the name. anybody ?
