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.
(.. Do you still spec that if metal is prepped down to shine?)
