Never got the answer
When asking if lacquer can be sprayed over rattle can Rustoleum primer. I'm asking because, after derusting the back panel on my '29RPU cab, I hit it with the rustoleum rattle can primer. I need to work the panel some more, and will need to eventually hit it heavy with a high build primer to get the rust pits filled. I intend to use Sherwin Williams primer in a lacquer base to get the surface filled. When I do, is it going to lift the Rustoleum already there? I guess if I can't get this answered, I'll just do it. Then I'll know.

Re: Never got the answer
I have never done this so I can't be sure it will work. But you might try a sealer like Velva-Seal on it.

Re: Never got the answer
In the future, why don't you try Napa brand lacquer sandable primer for temporary protection.

Re: Never got the answer
I'd suggest stripping that enamel can primer off and spraying on some lacquer primer. Then you won't have any base reactions going on between the two. Remember that primer looks like a nice hardened coat that we spray on, but in actuality, it is a sponge. This is why reactions can happen even after a bottom coat is dry.
If, like me, you don't bring the gun out regularly, or don't have one, here is just one link I found for Acrylic lacquer primer in a can: http://www.drillspot.com/products/50...ray_primer?s=1 |

Re: Never got the answer
I used the "Stops Rust Automobile Primer". I presume that is what you used.?
I have sanded most of it down, and have some left and some bare metal. I'm at the point that I wanted to change to acrylic lacquer primer to speed up my cure and work time. Whats left of the Rustoleum is pretty thin, so I guess I'll hit it with the lacquer tomorrow. It's been 4 days since I sprayed the Rustoleum. |

Re: Never got the answer
I'm pretty sure that all automotive primer used to be lacquer because it dried faster than enamel and you could sand it sooner. Also you could top coat it with either lacquer or enamel. The general rule is, you can spray enamel over lacquer....but you can't spray lacquer over enamel because it will "lift".
At least that's the way it used to be. It's been a long time since I've done any painting, so things could have changed a lot since then. Good luck. Stan |

Re: Never got the answer
You'll have to get the top coat paint to stick to that 'fish oil' primer. You just might be stuck with that Rustoleum family of products.
skip. |

Re: Never got the answer
Ask your top coat paint supplier. It's their paint and they should know what's compatible underneath

Re: Never got the answer
Well, after a trip to the automotive finish supplier here in town, and, $300 later! I purchased an epoxy primer and sealer as well as other supplies I will need along the way. I will sand as much of the Rustoleum off as possible, and follow with a "Kustom Shop" product - DTM Epoxy Prime/Seal. I will then use any filler needed, then follow up with their Polyester Primer Surfacer. Sound reasonable? Any further comments appreciated.
