Q: am smoothing the dash in my truck, involves sanding down to metal in places. is it ok to use a lacquer based primer and then be able to use ppg paint over this, or do I need to lay down ppg primer over the lacquer based primer? what is ppg primer's base? some one told me that if I used the wrong combination of primers and paint that I would ruin my paint job before I ever got started, so maybe I should trash the lacquer primer and go get some ppg?????thanks for your time, slaughter

Never spray laquer over enamel, enamal over laquer is ok. (just a big no no to guide you through the years)I advise to get some PPG primer, set the laquer aside and use it for something else, just use PPG products together to prevent anything from happening, even though something doable doesn't mean it should be done, in my eyes of course, others may say different.

Even if urethane primer is used it is possible for it to attack what you are spraying it over. Try spraying several light coats instead of a heavy one. If any lifting occurs I've had to use a waterbase primer to use as a barrier coat to help stop the lifting. The lacquer primer is aggressive, the better products today are catalyzed.
