I have some minor rust on my rear fenders. It seems to be under the paint. Is there anything i can do for this that doesn't involve alot of money?

 

nope. the only way is to cut it out and put new metal in. sucks doesnt it?

 

If you go cheap on it, the rust is only going to come back. As said above, you'll have to have it cut out, and a new piece welded in. Hopefully the rust doesn't extend too far on the inside so that it may be stopped.
