ive got a small patch of rust on the back end of my car from what i would assume to be an old impact from a shopping cart or something. its been there for years, but the moisture year after year is finally just beginning to eat into the metal. So far, the rust is just on that spot. It hasnt started eating under the paint yet. I know what SHOULD be done to fix it (i.e. grind it out and repaint the body panel. But i was wondering if any of you knew any ways or any products that i could use to seal the rust spot so that it doesnt continue any farther than it has. I have thought about carefully putting hot wax into the spot in order to waterpoof it. Any other ideas? The rust is only about the size of a nickel and in a concealed spot, so i dont really want to have a body shop charge me $$$$ to get it redone.
any help would be great. -Thanks.
