Before adding more materials should I clean the gun with Lacquer thinner?
The product can often cure enough to present a problem with clogging unless you are applying as a team where one person is mixing the next batch as another is spraying. It is recommended that you do a basic cleaning of your spray equipment between batches when only one individual is spraying. Partially cured truck bed liner or other coatings can dislodge and clog your spray gun, which may require you to dump the entire batch to clean the equipment.
We recommend you coat the gun and hopper interior with mold release agent, also called “LECITHIN” to allow you to blow out most of the uncured product remaining. This allows you to use less lacquer thinner. If lecithin is unavailable, Original Pam cooking oil (not the olive oil, baking, or other types) makes gun purging fast & easy. Just a light coat of these products will suffice.
