frame painting gaff

Whoops, the '71 frame has a coat of Rustoleum's rusty-metal primer on it now. Problem is that it went on a freshly-sandblasted frame, so I should have used clean-metal primer, right? Is it really that big of a deal now? Do I have anything to worry about?

The topcoat will be Rustoleum's oil-based enamel. I planned on brushing a coat of it on here today or tomorrow. Should I mix in a hardener additive? Why or why not? I don't want the frame paint to be soft.

Finally, anybody use a clear coat on top of the color coat? I thought about using a couple rattle cans of clearcote after the black topcote dries.

 

I've always just used regular Rustoleum primer on bare metal. I'm sure there are arguments for metal-etching primer, but the regular stuff has always worked well for me.

YMMV

 

You will be fine. I would have used the red-oxide primer myself. Clean metal primer is for clean, fresh metal. Even though you removed the old rust, it is still there microscopically. The most beneficial ingredient in Rustoleum red oxide primer is fish oil. and it works great.

 

Bet your OK with the primer but careful of the clearcoating not all are compatable and will will leave you a lovely wrinkle effect.

 

A metal etching primer and sandblasting seems redundant.

 

Actually, it was what I was told to do with some rusty areas of my tub.
The main part of the rust is gone, and the etching primer converts whats left into an oxide.

But then, I'm paranoid and didn't want to have to deal with rust again....

 

Thanks for the reassurance. The Rustoleum Rusty-metal primer is reddish in color. I have no idea what "self-etching" means, but it doesn't say it anywhere on the can. (reaching for dictionary...)
jd7--thanks for the clearcote warning. What should I use then?

Anybody want to take a stab on the hardener question? Thanks for all the responses.

 

look up rustoleums web site. they can answer all you questions. it's a very good website.

 

I'd be more apt to put hardner in the covercoat. Using synthetic enamal? should be able to buy suitable hardner where you bought your covercoat.I went back and checked your using rustoleum did they have an enamal hardner there I've bought it at tractor supply and used it worked fine. Just follw the directions you'll be ok.
