Need paint advise, Primed and ready for a final sand Options

[Lennies914]

So I've been preping my '75 for paint for the last two weeks and figured I was ready for primer. So I thought I'd do a quick wipe down with acetone and a tack cloth then shoot some primer. Had I been more experienced at painting I probably would have realized sooner that the paint (repaint) that I have been sanding on for two weeks was lacquer (IMG:style_emoticons/default/headbang.gif) . The acetone imeadiatly started washing off the old paint. So hear is my question. Is there anything better and cheaper than acetone to wash down the car? Assuming that I cannot paint over the lacquer with acylic urethane.

Hi Lennie,
First off I need to say that I'm just a hobby painter, thought I've been doing bodywork for the past ten years when I first started working on cars in high school. So if any other more experience folks come along, I'd follow what they say.

Ideally, we would want to remove all of that lacquer first. Urethane CAN be shot over lacquer, but long-term prognosis is not usually good. Are you just shooting 2K over the lacquer? You can use a product called Prep-Sol by DuPont, but being DuPont, it ain't exactly cheap. Most wax and grease removers sold at the FLAPS would work, I think.

So you've already bought the primer? Acrylic? You'd most likely want to continue with lacquer for primer, color and clear, IMHO since thats whats on the car now. But, this depends on what kind of longevity you're looking for and how much you want to spend. I'm all about urethanes, especially in humid areas. Lacquer tends to absorb moisture over time - thats what its a bit outdated.
