Protecting door Jams, rockers from rust.

[XLexusTech]

Not PT related but hoping its relevant. I have a GMC 1500 and live in the north east where roads get treated with salt. Rust is a problem ..

I was planning to trade in my 2017 soon but now I am thinking I might have to keep it indefinitely.

Curious if anyone has a product recommendation .. ceramic coating or corrosion product. that might actually work.. door jams and rockers seem to be a common rust spot on pickups..
