You make me blush

Q: My painter sprayed lacquer recently on a hot and humid day and trapped moisture under the finish. Having had experience with this I told him to re-spray with lacquer retarder added to the lacquer and to remove the humidity from the room before re-spraying. This worked to a certain extent but still did not get all the moisture out. Should we just add more retarder to the mix and re-spray?
A: Yes, exactly. Or, in extreme cases, simply spray pure retarder thinner which is available in convenient aerosol cans or in liquid form as “blush chaser.” If you go that route, be careful; you are spraying pure thinner, and if you get the finish too wet it could run.
