In my shop I use Lenmar "DuraLaq" which is a nitro lacquer, along with ML Campbell Krystal, and Envirovar which are both Conversion varnishes. I'm considering switching to Sherwin Williams products because they are right down the street and more convenient. The guy wants to sell me their "Low VOC" lacquer which is the nitro equivalent to what I'm using, and also their Water White Conversion Varnish, the other equivalent. Are any of you spraying these finishes? Do you like them?
