With this product, you can even topcoat
POR-15® that's been in place for months or years.
POR-15® Self Etch Primer is NOT a
high-build primer, like POR-15's HIGH BUILD PRIMER, but it can be
sprayed or brushed on almost any painted surface and can be top coated in 15 - 30
minutes. It bonds incredibly well to POR-15® Rust Preventive
Coating, and all topcoats bond incredibly well to POR-15®
Self Etch Primer. It can be sanded lightly, and, if desired, multiple
coats may be applied.
It is available in a large aerosol spray (15 ounces). In situations
where you are topcoating a very old POR-15® Rust Preventive Coating finish, we first
recommend a light sanding with any 280 to 320 grit paper.
