I don't think you will have any problems with the oil based paints, either as a base coat or top coat. Generally, you can paint oil based paints over lacquer, but can't paint lacquer over oil based paints. But you will be applying a very small amount of paint (the webs) thinned with a very small amount of lacquer thinner. In order to do one machine (cabinet and head), you will not even use 1/4 of a can of the Krylon Marbellizing paint. I think I thinned my paint with about equal parts of thinner....won't hurt to thin less, but may not siphon out of the gun if too thick. Not sure about using a HVLP gun. I didn't try that. Crank up the pressure to about 40-60 psi and practice on some scrap. Really it's easy. Play with the mixture flow adjustment and practice moving the gun fast enough to spread out the "wisps" of paint.
