The ReRanch brand blush remover is aptly named "Blush Out". It is formulated to remove moisture blushing in lacquer. Moisture in the air can cause a white film in lacquer coats. It is especially noticeable on dark colors and black. Blush out reflows the lacquer and allows the trapped moisture escape.
Blush Out could also be called "Burn In". It will soften old lacquer and blend in new coats without the so called "witness line" between the old and new coats. If you finish or refinish with lacquer you need a can of Blush Out on your workshop shelf.
