Thomas,Bob P. and Tom S. nailed this one,they did and still do use nitro laq.Plus there are alot of little tricks that they did.You can still buy the Pravail spray cans to mix your own paint I think.If you're new to spraying,practice on a sheet of glass first until you cover good without runs.That's the best beginner trick I've ever seen.Most fine guitars,etc use nitro but it may be alittle to soft of a laq(they expand alot)you can search Les Paul,etc to learn about it.I hate to admit it but Home Depot was selling a hard nitro laq but I never tried it.Parks was the brand name.Never use Pledge on anything and don't put salad dressing on your cabinet.Charlie
