They had this mesh looking stuff at the store, had adhesive on the backside, I was thinking about getting some of that but then I thought about it and realized that it's probably not the best stuff to use when working w/small, concave area. Now if I was fixing a rust hole or something, no problem. I think im still gonna use fiberglass and bondo. Using bondo only just doesn't seem too good of an idea, I'd feel alot better knowing that I have some glass on there for the added strenght and support. The part that scares me out of it all is the sanding part, I don't have an electric sander and im just worried that it's not gonna be as clean and smooth as I'd like.
