Would RecommendI used this to repaint metal lawn ornaments and it worked well. Rust-O-Leum paints usually hold up too.
Rustoleum Good as Usual
Would RecommendSprays on smooth. Seems to adhere quite good. 1 coat wet sanded easily. Covered quit well with Rustoleum paint. Good, like other rustoleum products I've used in the past. Time will tell if it keeps the trailer hitch from rusting again.
Good Primer
Would RecommendUsed this spray to fix some rust spots on my car. Primer went on smooth and sanded very well. Once painted the spots were very hard to see. Like other products from this company I would rate this an excellent product. The directions have the usual temperature, humidity , and cleaning precautions.
Terrible Product
Sprayed sprayed smooth (400 grit) metal, wiped down before, let stand 10 hours until next morning, 90-95 percent wiped off with a paper towel next morning. It’s was crusted up, never seen anything line it will have to resand

Great General Use Paint
Would RecommendI was making a product that I didn't want to use flat pint on... just doesn't look well made. Really glossy paint shows up fingerprints and such way too much... so I thought I would try this. It's like the story of the three bears here... The first one was too flat... The second one was too shiny... And this one is... wait for it... Just right.

Pretty poor grade of primer
Would Not RecommendI sprayed a perfectly pristine piece of aluminum with this stuff and the next morning I could scrape the dried finish off with a fingernail.
Something is amiss here, Ed! Our Rust-Oleum Stops Rust Automobile Primer dries very quickly, and should be dry to handle and sand in 15-30 minutes. W...
