Evercoat Uro-Fill Activator

Use Evercoat Uro-Fill Activator with the Evercoat Uro-Fill Primer Surfacer (sold separately). Mix one-part Activator to four parts Primer Surfacer, and when the products are combined, they provide superior adhesion to bare steel, body filler, fiberglass, and treated aluminum. You'll be able to easily finish sand in one step with fine grit sandpaper. The two components provide a thorough cross-link cure with no shrinkage. For priming/surfacing auto body repairs prior to topcoat refinishing, use these quality products from Evercoat.
