I've got some paint wearing off on the door sill edge, right next to the nerf bar where I step to get in the truck, also a couple deep scratches next to the tailgate handle from dropping it on the trailer jack handle by accident.


I'm not looking at sanding down the area and spraying it, they aren't visible areas at all, tailgate ones are covered by the bottom of the cap glass hatch and door sill isn't even visible behind nerf bar really
Just want them covered for rust protection.

What are my options for application other than a spray can?
Anything other than the nail polish type thing?
And where do you order them?
Thanks
