HI,
I seem to remember in the (old days) people said you could paint enamel over laquer but could not paint laquer over enamel.Can any of the "new paints" be applied over laquer? If not is it true that enamel can go over laquer?What procedures do you have to follow?As you have probably guessed by now my car is in laquer and I want it to be in flat or semi-gloss black,and I would like to do it without stripping all the old paint off. :confused:

If you will NOT strip the car then you should seal it with epoxy primer. You should not reduce the epoxy (the reducer can react to the laquer). if you are doing a simple repaint and do not need to use a filler primer then I would do this: sand the car with 320 and then put on 2 coats of epoxy. let the epoxy set up overnight and then paint the car.

IF the car needs body work and high build primer then I would do this" sand the car with 120-180 and then 2 coats of epoxy. let it sit a day and then do your body work, spray the high build primer, block it out and paint the car.

I have also done this: sanded with 120, then put on three good coats of polyester primer (i used fetherfill G2). I did NOT add aceton or reducer. Spray the poly with a large tip (2.2 is great). then I blocked the poly, sealed the car with a coat of epoxy and base and cleared the car.

If you want to be on the safe side strip the car. I have used the above ways and not had problems.
good luck

eeeeh .... depends on the epoxy primer... ppg 271 will DESTROY lacquer .... the 271 shrinks alot as it dries, and the entire job looks like an earthquake hit it

it took me 2 days to fix the primer on my bosses friends car, 2 full days between the first coat of primer and the point when i was able to say "paint it"

every new coat of 271 caused 1/2 as many cracks as the last coat, leaving me with more sanding to do every time, the last 3 coats of primer caused one crack each, and the last crack was nearly vertical, so i just poured some primer down the side of the car over the crack and walked away till it dried

thank god the entire "show quality paint job" on the car was as wavy as a small pond getting hit by a large meteor, otherwise i would have had 2 more days of work to get the door straight

I used omni epoxy and did not have any trouble...have heard of all kinds of problems with painting over lacquer. So to say it again: to be safe strip the crap off and you will not have to worry.
you can spray AE over epoxy or a 2k (high build) primer.
