Colad Snap Lid system is designed as a paint application system suitable for all types of paint. We’d advice to check with your paint supplier with micron to use for a specific type of paint. In general the 90 micron filter can be used for clear coat, the 130 micron for waterbased base and/or clear coat, the 190 micron for conventional base coat and the 280 micron for primer. However this might vary depending several conditions such as the recommendation from the paint manufacturer.
