Paint Over Rust?

[txdon]

OK Bird, My solution is a combo of the above with a Harvey twist.

On the old pitted rusty cattle guard I got from Mike, I put the "Ospho" from Ace and then I painted it with Harveys special Mixture of 1/2 Rustoleum Rusty metal primer and 1/2 Leather Brown Rustoleum paint. The is no rust after 4 months and the part that I drive on stays on just as good the parts I don't drive on. Tough stuff.

The Ospho goes a long way and a quart might be plenty.

The Ospho is something new to me; don't recall ever hearing of it before.

Bird, how large is this shed? For the materials and labor, you might be able to buy a new one that will last longer. $259. for this one.

Jim, that looks like it could be the same storage shed. Theirs is white instead of gray and I think the roof was red. So I know they don't want to spend a lot of money on it; just would like it to look a little nicer in the backyard.

BB, Rust reformer actually is white, but turns black when it contacts oxidation. I love the stuff and have used it since the '80's, but it is not cheap, or even reasonable, in price.

Maybe there are different brands of it. The one he used (the link in my post) actually sprayed on black, even on clean non rusted metal. The web site states it goes on flat black but can be painted over in any color. I was with him when he bought it at Walmart. I did not really pay attention but I didn't think it more than $6 or $7 per spray can.

I have a 300 gal diesel tank thats pretty rusty looking and decided to try a little test with some Rustoleum spray can primer. I wiped off about a 12"x12" area with my glove to knock off the dusty stuff and sprayed the primer, no paint. It has been a year now and the rust isn't showing any signs of coming through yet. So this spring I plan on sanding it lightly then prime and paint.
