hey guys, i'm in some need of some advice, over the past few years, my camaro has been sitting out in snow, this year when i was prepping it for winter time, i looked underneath and noticed that the rear frame rails are looking a little flaky, there is no rot, but i'm afraid that they might rot this winter, what i did was wire brush them and i threw some paint on it, i'm hoping that that does the job, but i'm not sure, and i was just wondering, how hard would it be to replace them, if in case they do rot out, if you guys could send me like a procedure of things that i would need to do and what i would need to do it, thanks in advance for any help.
