Rustoleum vs Rust Bullet

[Brentbba]

I've got a '92 M101CDN trailer I'd like to repaint. I've been doing a lot of reading in this section. Typical Mud - lots of knowledgible guys very willing to help and share info.

The M101 doesn't have much more than some surface rust. A little scraping, wire wheel/wire brush can remove the stuff that's bubbled under the paint and there's still a very solid surface beneath it. No rot thru anywhere.

Is it worth the $$$ for Rust Bullet, or for a trail trailer, is Rustoleum Rusty Metal Primer and Professional High Performance Enamel going to suffice for both the underbody and body? Ive read too many comments about the rubberized underbody coatings drying up and flaking off, so doubt I'd go there.

Cost is an issue, otherwise I'd wheel it down and have the body/frame sandblasted and powdercoated or professionally painted.

I've already taken a high pressure washer to the entire trailer, so she's squeaky clean right now.

Any other prep hint or tips.

TIA

if that was me i would wire wheel it and paint it with rustoleum or similar. that being said a small can of rust bullet isn't a lot of money, then rustoleum overtop.

Have you actually put an Alkyd over a Moisture Cured Polyurethane? - I have and the Alkyd crinckled, fortunetly it wasn't for a cosmetic repair.

For the rust repair I did, I brushed on one coat of Rust Bullet Automotive Formula, which emptied that can of Rust Bullet. Then 24 hours later I brushed on another Moisture Cured Urethane, this time a KBS product called BlackTop. Then four days later I brushed on one coat of an Alkyd paint made by PPG in Australia called White Knight Rust Guard Epoxy Enamel.

The KBS brushed on better than normal paint until about three hours into its potlife when it became too tacky and wouldn't flow from the bristles. Where as the Rust Bullet never brushed on well, probably because it's too viscous.
