Would Not RecommendThe project im working on now is a large gooseneck trailer thats sitting outside, having used about 4 types of primer over the course of the restoration I can honestly say this is the best rattle can spray quality, but it has been the WORST at preventing rust in between coats, sometimes 3 or 4 days in between. Its been 3 days and rust has started penetrating the primer coat. Its so bad that even some of the finished areas that this primer was used on are showing rust through the finish coat. Whi...

Excellent!
Would RecommendThis primer has proven to be an easy-to-apply, fast drying, durable primer that lends itself well to DIY metalworking projects. Many times these projects sit and wait 'til I'm able to devote time to them and spraying bare metal after welding, bending, etc. keeps it from needing to be further prepped before final paint - preventing the pieces from rusting. It's money well-spent.

Used it on an old wagon
Would RecommendI scraped off the old paint as well as I could with a wire brush. Then sprayed on the Rusty Metal Primer. Followed that with another Rust-oleum spray paint. It worked well. It will give us another year or two wear out of that old wagon. I was very happy with the results.

The spray tip cloggs too easily
Would RecommendAfter several uses with a substantial amount of time between uses, the spray tip clogs with dried paint and I haven't found a way to un-clog or prevent clogging. Maybe a redesign of the spray nozzle is required.
