I have a 94 and my entire passenger side floor pan is starting to rust and get soft. I think a defective cat sped up the rust problem. I replaced half of a completely worn out part where the carpet was the only thing between me and the ground and now i'm gonna start to redo the rest but i wanted to know what you guys thought would be a good Undercoat to guard against water and dirt and stuff. I was thinking about POR 15 and that line of products. I live in Fl if that makes a difference.
