This special "interlocking" primer was developed after many requests from customers who wanted a coating with special adhesion characteristics that make it perfect for most painted surfaces, especially POR-15® Rust Preventive Coating.  POR-15® High Build Primer is also highly resistant to penetrating topcoats, like lacquers, enamels, and two-component finishes. It sands very smoothly as well. Try some on your next project.
