No problem with doing that. Lacquer over enamel can be a problem....chemical reaction causes the enamel to wrinkle/lift. But enamel over lacquer is fine.
Hey, Is it your intension to put a real paint job on this project, or just a ''quicky'' with a short life expectancy? Lacquer primer or primer surfacer is not renound for its' adheision properties or its' ability to stop moisture from reaching the metal beneith it. True, we used it beneith both lacquer & enamel jobs for years, but as time went on better products came along. If you are going with a real paint job, I'd jump up to a full urethane primer, that's both weather proof & offers great adheasion. Today's primers no longer contain the heavy metals they once did and your defence against rust and adheasion problems is the urethane or epoxy resin contained in them.

All of the primers I have ever used in over fourty years of putting on paint were 'laquer', (they cure by the evaporation of solvent)
Im old fashioned and use laquer primer and then do an enamel job. I like the old school method because of cost ,Sure there is better primers and sealers ,out there ,If its garage kept and taken care of It will last 20 years or better ,Outside sunlight and changing of seasons and especially rocksalt are what causes the damage...............
I wouldnt only because of the different expansion rates of the two. Lacquer expands and contracts much more than any other paint and will case small spiderweb cracks.
The use of lacquer primers prolong the process because you have to wait for it to shrink and thoughly dry before the sanding for the next step. I've used both epoxy and lacquer; epoxy seals and preserves the metal underneath. JMO
sure you can, wet sand with 400 grit and use a good grade sealer. quick question though, why laquer primer? is it cost or lack of controlled enviroment for spraying? the laquer will eventually fail one way or another. sometimes (and maybe not in you case) it pays to spend a little more if you want the job to last. prep is everything and it starts with good material.
Laquer primer is junk but if its all you have then so be it. I get epoxy primer around here for 140 for a gallon and the hardener. Obviously makes 2 gallons and works like a champ.
A long, long, long time ago we used nitrocellulose laquer for the finish coat. When we started using enamel finish coat we just never started using different primers. Even with I***** we used lacquer primer. I have never had the 'spiderweb' or 'cracking'. Possibly people that do put second coat on before the first coat dried? I dunno, maybe they try to put it on too heavy? I was taught a certain drill, thin it right, use a flow funnel to test viscosity, spray it right, at the right temperature, never had a problem. I have never used anything else but lacquer primer, other than a couple of times I tried epoxy, found it to be a h***le, mix the ****, either mix not enough and **** around mixing more, or waste the leftover because I mixed too much along with the higher cost. For me it's not practical, since the results can't be compared, don't know of any tangable advantage of either after it's covered up, I'll stick with lacq. When I'm done I strain what's left back into the can and it's good to go for the next time.
