Due to the nature of the chemicals involved in this exercise, you need to have proper tools, equipment, and protective gear in place.

These include a face mask, an apron, and overall, stick, warm water in a bucket, and unusual containers. More importantly, it would help if you had a thinner, and this may be Lacquer thinner, turpentine, or mineral spirit.
