Reusing the Powder
Powder swept from a clean tarp can be poured through a strainer for reuse. You can only reuse it when you are positive that you had a clean drop cloth and the powder is not contaminated by any foreign matter. Contaminated powder may cause pits and orange peel. Contaminated powder can be safely disposed of in the trash.
Caution: Before reconnecting your powder gun be sure to change the air pressure from 30 psi back to 8 psi ! The cup and lid assemblies are designed for no more than 10 psi. Replace your moisture filter regularly, as moisture will build up even when the gun is not in use.
