Gee whiz, it's white car... the guy could have saved everyone all this trouble by just using white Rust-Oleum! Or maybe you could put white R-O over that with no issues?

Maybe!? Or like said, do it right and get it bare metal and .... Like GeorgeH said, BE sure not to use a self etch over it. I guarantee it will booger...seen it
I have used TCP Global products with a lot of success. They have a Direct to metal epoxy. they call it, that seems to stick very well to a lot of surfaces.

The car is going to be painted RED. If it was staying white I would have painted it Rustoleum white!
 
Well, I can tell you if it was my paint shop I wouldn’t touch it with a 10 foot pole. It would go to bare metal, because that’s the only way I’d be comfortable putting my name on it.

Obviously doing it yourself is a totally different story. It’s just what you’re willing to risk. But personally, I’d strip it. You’re talking about what, a day or two of labor to get it back to bare metal? That’s not much gain. Meanwhile, you risk ruining a batch of primer at least, after which you’d have to go bare to metal anyway.

The other thing is, it may not end with the primer. Sure, the primer might lift, wrinkle, or obviously fail somehow. But, it might also react and cure differently without lifting. And then the topcoat might not lay over the primer, it could react and wrinkle or lift too. They call them paint systems nowadays for a reason. Still up to you if you’re doing it yourself, but you could be risking the primer and the topcoat. There are chemical reactions that take place between each layer, mess with one and it can effect all of them.

With what paint costs, I’d just do the labor the first time around.
 
Like I said earlier I'm going to do a small test area before I decide what to do. The car is going to be painted bright red and I would like the engine bay to be the same color as the body. Hell Rustoleum makes a really bright red I may do the engine bay with that and have the paint shop mix some paint to match for the rest of the car.

Old post, I know - but I'm curious how this turned out? What did you end up doing?
 
Old post for sure. I wish people would do a better job of following up with us so we know how things turn out! Regardless, here is my $0.02. I agree with a lot of the advice given. It could quite possibly be OK using that black Rustoleum as a base. However, I would not do it. It wouldn't take that long to strip the paint off with 80 or 120 grit. Then, from bare metal, a person would be free to do their thing. I am kind of anal when it comes to paint prep. Unless I absolutely know how things were prepared and am comfortable with the application, I don't trust unknown situations like this. I am absolutely not disagreeing with any of my FABO brothers who posted above, that's just how I roll. I have a friend with a 70 Cuda. He bought it sprayed with polyester primer and said the guy told him it was "Ready to Paint". I told him I would be the judge of that. So we put some guide coat on it and blocked it all off, and guess what? It wasn't really "Ready to Paint" at all. I fixed all the bad places, primed it again with my favorite primer (Evercoat G2) and blocked it again with guide coat. Then it WAS ready to paint. I rarely trust other people's prep work. That may seem a bit harsh, but it is the result of many experiences. I wonder how many times @Oldmanmopar has been told, "It's ready to paint. I just want you to spray it"?

I have been working on a car for a friend for a long time. I have refrained from using rattle can stuff except for a guide while knocking filler down. It pretty much all comes off and its just a dusting. I like the metal work, hate the finishing. Lets put it this way, if its my junk i’d paint it with a mop.
I met a fellow that hates metal work and likes filler work and paint. Was reccomended by a paint supplier. My job now is to assemble it and line up panels as best as i can. Then ship it.

Absolutely!! It happens far to often where people ask for and receive feedback never to be heard from again. It's nice to see how things turn out because people tend to have the same questions later on. It kinda makes the search function useless when the results aren't posted.

All of us car nuts are in a continual state of learning. IF we are actually doing something.... It would be great if we would all think to share our latest knowledge. Many times we don't because we get tired of having people tell us just how wrong and stupid we are ...maybe?????

I have NEVER top coated a car with Rustoleum I am doing any body work on and never will. Reasons should not have to be explained. But I have used it on clean rust free or rust cleaned off floors for 60 years/ and inside doors and inside trunk drops on trunk side. BUT my dad back in the 60s told me the stuff was not worth a chit since they took the lead OUT of it!!!! He did have a point back then. Study up. Are there better paint/primers today? Yes. Does the most expensive matrial always \prove to be worth the cost? Not always. Just my old opinion.

Indeed. In fact, I often thank the person for getting back to us with a report on the outcome.
