Protecting door Jams, rockers from rust.
 

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..

Do you mean they just rust there in general or they typically rust from the inside? I'm not following 100% but Eastwood make this internal frame rust encapsulator setup that's cheap and looks easy to use for better protection.

What I mean is the area traps slush and ice.. which are like. giant salt rocks.. at sit on the truck... and the door jams.. ice and salt sit in that area..

Oh I see, my idea won't work then, not quite sure what will

Both 3m and wirth make a cavity wax . It's not an oil that makes all dirt n crap stick to it, or in the summer heat the oil drips everywhere. It's a spray wax that drys ,leaves a film ... Google it

Made with special rust and corrosion inhibitors. Excellent on metal surfaces, leaves a long-lasting protective coating. Protects against the effects of salt, moisture & chemical corrosion. Works as an undercoat, leaving a wax-like amber film.

is it for painted surfaces or raw ?

It will leave the film on both. The paint has the metal sealed but if you have unprotected metal then this will protect the exposed metal.
