Ok, so I'm 17 and I just bought a 94 jeep wrangler. It has rust problems all over the bottom and it's starting one hole, as far as I can tell its just one. The hole is about the width of my thumb. I was wondering how or if I can stop the rest of the bottom from rusting further and if I can patch the hole somehow without needing to cut a chunk out of the floor. Once again I'm 17 with low funds for now and low skills with cars to match. Plz help, I'm scared that the hole will get bigger, thanks.
