Back in the 70's when I was painting cars and motorcycles in lacquer it was common practice to apply 2or 3 coats of clear lacquer over the color coat with wet sanding between coats to enhance the depth of the shine. When good acrylic enamel hardened clears came out we used to shoot a coat of clear Dupont Centari clear over lacquers for the cutomers that didn't want to pay for the final sanding and buffing. The lacquer was very easy to work with. You could correct any body work issues and recoat all in the same day. Follow up with the clear and you had a nice shiney durable paint job for a driver. Show paint was several coats of clear lacquer over color sanded and buffed.
