Frame rust

[jcalifas]

Hey does anyone know how to prevent the frame rust? I see alot of repair and replace but no prevent.... Drill drains, spray rust killer inside, any ideas? Thanks guys and good wheelin.

I rinse inside my frame well regularry (all my factory drains are clear), especially during salt months. The outside of my frame (all 4 sides and cross braces) is painted with brush on bedliner. That's my regime for keeping it together longer

Your frame should already have quite a few drain holes......that being said there are tons of ideas/methods, just pick one and give it a shot. I like the idea of buying a cheap garden pump sprayer (Home Depot, Wal Mart) and using your choice of oil/atf/rust preventive and just coat the inside of your frame rails. Or you can buy

Lots of other store bought stuff, but I know someone who used that and he said it worked pretty well.

Keep the drain holes clear, rinse it good and dont get mud in the frame. I would say you could punch a few more drain holes, it shouldnt hurt anything and the factory ones plug up real easy. Fluid film works good at stoping mud build up and salt.

 

You can undercoat/ paint the inside, but it may take a while.

I've heard that the wax-based anti rust stuff ends up trapping water, so I'd avoid that. Next time I change a fluid out I'll probably try the pump sprayer idea.

 

It's a whole lot easier (esp. on a stock-height truck) to spray out the rails with the rear wheels or bumper removed. With the wheels off, you can get to the cleanout holes; with the bumper off, you can spray right down the frame rails. I don't wash mine out very often, but I don't take it mudding, either. (And Washington doesn't use salt.)
