The local NAPA store keeps it in stock...qts and gallons. There was talk 5-10 years ago about outlawing it but it didn't come to pass...at leasat not here in rural Wasington State. The difference I'm talking about is hard to describe and I don't know if luster is the term I would use. Over the years we've always talked about black laquer as looking like black metal and urethane looking like metal covered with a deep coating. Both great looks but two different looks and textures.
