Absolutely. POR-15 will accept all paints, including lacquer-based paints. POR-15 Tie-Coat Primer is the best prime coat to use before topcoating POR-15. Be sure to read thoroughly our directions and tip sheets regarding topcoating before using POR-15.


WHAT IS THE BEST SURFACE ON WHICH TO PAINT POR-15?
POR-15 likes rusted surfaces best. Seasoned metal and sandblasted metal are also good. POR-15 does not adhere well to smooth, shiny surfaces, but will adhere well to those surfaces with the proper preparation.


WHAT IS THE 'PROPER PREPARATION'?
We make a product called 'Metal-Ready'. It's a rust remover that leaves a zinc phosphate coating on base metal, the perfect preprimer for POR-15. NOTE: New steel is coated with a protective oil finish at the mill. This finish must be removed before using POR-15 or Metal-Ready. Clean metal first with POR-15 Marine-Clean, then rinse with water and dry.


CAN I USE BODY FILLER OR PUTTY WITH POR-15?
Yes. First paint both sides of the rusted area with POR-15; then use body filler or putty as soon as the POR-15 is dry to the touch.

Hope it works for you. It sticks best to rust, but remove the rust first with metal ready and be sure to seal it in with their tie-coat primer before you topcoat?
