What specific problems do you have? Treat it the same as acrylic lacquer. Without being specific lacquers require more aggressive sand paper grits and polish compounds. I would probably look at the Mcquires line up for products and/or ask them for recommendations. Most of today's products are intended for use on modern finishes chemistry.
3M or Dupont is what I use, I am not sure that they are not the same company. The products seem to perform the same. Rubbing compound than glazing compound as has been noted by John here.
Question..how does wet sanding with 1000, 1500 finishing with 2000 and using foam wheels work?? Kinda like what we do with enamel. Granted it's an old paint job so wet sanding with 1500 should be enough but can I still use the foam wheels. I use a 2 stage buffer.
That's exactly what I started today. Soapy water and 1500 sand paper to start and finish up with 2000. It's starting to check in different places but that really doesn't bother me. It's a driver not a show car. I just sanded over the checks and consider it patina. LOL It has been a good while since any paint issues had been addressed and it has it's share of rock chips. I just hope it shines when I'm done sanding and buffing. All I have is foam pads, look like i need to get me a wool pad before I start buffing. Thanks for the heads up guy's.
I was a Nitrocellulose Laquer guy in the sixties and we would sand them with 600, buff with aggressive 3M compound and cotton pad. After we would use 3M fill and glaze (pink) and a soft pad. Be sure to check the film thickness before you start as you may not have enough material left to do this. Good Luck, Joe
