I just picked up a can of Lenmar Megavar conversion varnish (standard, not high-solids) for refinishing a dining room table top. It will be my first experience with conversion varnish. I'll be spraying it through a Earlex 5500. Can anyone offer pointers for:
- appropriate thinning (%, lacquer thinner? acetone?)
- needle size
- need for retarder (spraying outside with temps in high 70s, moderate humidity)
- # of coats needed if thinned
- other pointers?
