what type of rust prevention are you talking about? you have an 80 frame? so i take it you have some rust.. well they make this stuff.. rust tough... and you spray it on over rust.. seals it. seams like good stuff..just used it on a tj frame that had some rust on it. i will say do not use por-15, unless its rusty. it will not adhere to paint.. only rust.. those are good for rusting surfaces, if its not in bad shape.. try a good thick paint.. i am about to use some "hammer paint" they use it on tool boxes.. putting it on mine wed.. if weather holds.. but that is a thicker paint.. and should do well on a frame.
