Are you using SU470LV 1K adhesion promoter when painting plastic parts? If so, make sure you hand shake thoroughly before use. This product contains a small amount of pearlescent pigment that allows you to see where the product has been sprayed and shaking ensures uniform application.

And if you’re using the aerosol version, SUA470LV, don’t forget to shake this as well! This will help prevent clogging of the tip for a smooth application.
