I'd read that post on the Wrangler Forum before. The post with the rusty pics was scary to look at! My son had used it previously on his 1964 Ford pickup. I did all the rusty areas on my Jeep last fall. My JK's previous owner (they bought it new) were from Massachusetts, so you know they use a lot of salt up there. You are in a suburb of Philly! Not too far away from me at all! Maybe we can get together some day. Owen
