When I use CA the fume situation is under control using an exhaust system through the roof to atmosphere the intake is immediately above the working area on the lathe. Just as important to remove the fine dust from timber turning as well.
Using a laquer also requires care and precautions. Just saying is my way of commenting thats what it is. As you say Walter I do not recommend but like you have an opinion.
Mind you I do not ever exceed three coats of CA.
