Scotty, I live in Minnesota, and I have a 2010 GMC Yukon XL.
It had rusty cab corners, So I sanded them, applied bondo, sprayed rust remover, then painted them. In 5 months the rust started to come back. Even after washing the car a lot in winter !! GRRRRRR
Other than welding on new metal, how can I eliminate these rusty cab corners ?
Rust, like death, is just an inevitable fact of life
