OK guys like most of you i'm a detail freak with my stang. I have no problem with the outside wash wax etc. the problem is in the engine bay. I have bolts and nuts in there infested with rust. I clean the engine regularly but i still get it i try the old wire brush and silicone but i dont like silicone all in the bay. i checked www.stangworld.com for info but cant come up with a definitive solution any tips or ideas are welcome.....how do i keep rust off my engine?
