Trailer painting options

[mlasal1]

I have this trailer that i would like to paint the underside of. It looks like it was probablly
never painted from the factory. Luckily im in south louisiana so the rust isnt terrible. Just heavy surface rust, no pitting. Id like to hit it with some paint that will help it last a little longer. Top side will be left alone for the most part. My question to you is what do you recommend as far as paint? Cost is a big issue. Second is durability. It doesnt have to be perfect or even look good. Anything will be better than how it is now. My only rules are no spray cans and no bedliner.

Also, Should i take the decking off and try to paint it from the top, or use the tractor to turn it on a 45 degree angle or so. Im worried about rolling the tires off the bead with this approach. Would love to flip it over, but i feel that would damage the fenders/light brackets and maybe even the sheet metal.

Like i said, not looking to go all out on this. Just want to get something on there for peace of mind

I would remove the bed first then wire brush or sandblast the frame. Use Rustoleum rusty metal primer and then paint with Rustoleum. Low cost and will last a long time.

To try and restore a car with this stuff on it is awful when attempting to remove, But for the use on the underside of a trailer I think would be the quickest and easiest method, If reason being only for protecting the underside from the elements, Although you did mention no spray can applications and I don't know of any other DIY method, Could be a commercial application of sort out there somewhere though,

+1 on Rustoleum for economy. Should be less than $125 in paint, brushes, rollers etc.

Or a Raptor bedliner kit to spray it. A good option for about the same $125 that Ted mentions. Why bed liner is not an option to the OP, I have no idea.

Agree with that as a recovering restorer, rustproofing is the cheap way out that you will pay for later...Kinda like digging a hole and burying a stump in your yard, it'll get you later....With all of the "C" channel under there a can or spray gun is the only realistic option to do it right and somewhat painless.
