Wife's Equinox has been plagued with rust along the bottom seams of the front doors. Dealer slapped a coat of paint on while it was under warranty, but that didn't last long. A couple weeks ago I realized the front doors were looking sad again, so I took a wire wheel to the inside bottom edge seams of the front doors, sprayed two coats of Rust-oleum Rust Converter on them, and sprayed over it with two coats of spray touch up paint. Right rear door was showing signs of the tin worm too, so I did the same for that one. Now, just two weeks later, brown spots are already appearing after a couple of rains. Now what? Touch up the spots? Spray over with clear? Start saving our pennies and trade in this reincarnated Vega?
