body rust- what can i do?

I just got a leer camper shell and had to take off the cheap plastic liner to get it to fit properly.
Well after I took it off I discovered that it had scraped off some of the paint and has started to rust.
I dont really care about repainting it as its not too noticeable, but is there anything I can do to keep
the rust away?

 

I'd sand it a bit and see how extensive the rust is, if it continues under neath then it is probably rusting from the inside. Slap some rust-mort on there, fiberglass filler, sand and paint, drive til you have to do it again.

 

thanks magog but do you think there is any way to just apply a clear coat on top after sanding and not worry about painting or would that not work?

 

If it were my truck I would sand ALL of the rust down to the metal and primer it and paint it and then clear coat it. It isnt going to look perfect, but atleast you dont gotta worry about rust.

 

If you can get down to bare metal that is the best but if the rust is extensive and coming from the inside then you may just want to do some cosmetic work. Once sanded down you can finish it as good or bad as you like. I'm a firm believer in the rust stabilizer products, they aren't perfect but they will extend the life of the metal.

 

Thanks for the help guys! Ill try and take smaller pics next time

 

spray bomb it with primer
