Default Clear Coat over Lacquer

Does anyone with actual working experience know of a clear coat that can be applied over some small areas of well cured and in good condition acrylic lacquer?
Some newer urethane clears are evidently not compatible according to some, but not all vendors.

years ago we sprayed several coats of clear acrylic lacquer over a lacquer base color mixed with metal flake to give the finish depth. As to working with a old well cured base, I'm not sure. If memory serves me you can spray Acrylic enamel over lacquer, but not the other way around so clear enamel should work, but I would talk to a auto finish supplier.

Like it has been said, talk to an auto finish supplier. Years ago I did the same thing with a Camaro I had whose laquer paint was starting to show the inevitable spider cracks. So I clear coated over it and sold the car before it could come back!

Why not go over it with Clear Lacquer, ... It will melt right into what you have now, a perfect match. If you use Clear Lacquer you'll probably be able to spot paint it instead of doing the whole panel if that's what your looking for

Lacquer not available due to VOC 's in many states. Some suppliers don't appear to know what won't melt or lift the lacquer.

I live in California and I am able to get lacquer from a paint shop in Arizona that deals with Classic car's. They would mix my color's and ship it to my house. I'll look for a can and post the info.

THE LAW in California.

If your a business and spray MORE than 50 gal a year, ... you cannot legally use lacquer UNLESS you get a statement from 3 paint mfg. stating they cannot mix that color in anything but lacquer. If your under 50 Gal, ... Spray Away.

Remember, ... Krylon is sold throughout the country WITHOUT LIMITATION other than age and it is a lacquer. The Green Engine paint we love and use, ... well guess what...

I ran prototype shops in California for 30 years and this is how one escapes the law.

BTW, ... If your spot painting clear, ... they sell Clear lacquer in a rattle can. It's all in the buffing when it comes to lacquer.

Regards
Bill

I have done several cars in lacquer colour then 2K cleared over.

No problems even years later.

As this is obviously not recommended by suppliers, my own judgment was to leave the lacquer for an hour to dry a bit before proceeding with 2K over in the usual way.

[B]I had a '46, Baby Blue Fast Back Chevrolet. Body & paint was PERFECT, BUT the paint was oxidized like Blue Chalk.
I scrubbed with T.S.P. & 0000 steel wool & sprayed it with clear Lacquer & was like a NEW PAINT JOB!!!
