Hey guy as some might have read Im redoing everything on my car and the first thing to get worked on is the black int cnversion, and the bdy. My friend has all the stuff I just wanna know how I get rid of the rust in the wheel wells. Do I grind it out and fill it in with bondo?
I would get rid of as much of the bad metal as possible, as stated in your title it’s like cancer it will spread. So do your best to clean it up, if you leave a big hole then you’ll probably have to cut some metal to fill it in with. Also, I’ve heard that putting Rust Inhibitor on the metal before you bondo/fiberglass will help keep it from spreading (I’ve not tried this myself) I prefer using short strand fiberglass like Dyna-glass for filling in holes and then use a finish coat of bondo. if you take your time sanding and put on 3 or more coats you should be able to get it to come out decent.
