Basic OptiFlow Epoxy and Urethane Primer Kit - Automotive Roll-On Paint - Black

While the OptiFlow epoxy and urethane can be applied with any type of paint roller, the results will be far less than satisfactory and you will have poor coverage, as well as pinholes and trapped air because standard rollers are not designed for this type of coating. To get optimal results, even coverage and to limit sanding, you will need to use the rollers designed for the OptiFlow Primers. The larger 7” roller is ideal for large, flat panels such as doors, hoods and roofs. Use the smaller 6” Roller for roof edges, windshield pillars, body line contours and tight spaces where a large roller can’t fit.

Why do I need to use this primer rather than standard primers?

Both the OptiFlow epoxy and urethane surface were formulated to provide maximum corrosion protection, adhesion and topcoat durability. A proprietary under-indexing of the Acrylic Polyol’s provides the coatings with superior flowout in the roll-on application.
