What Steps are Required when Applying a Top Coat over Rust Bullet?
Ideally, a topcoat should be applied between 24 to 48 hours after the final coat of Rust Bullet. It is necessary to allow enough time for the curing or gassing off process to complete. The application of a top coat before this process is complete, may result in dimpling of the surface and an undesirable finish. If more than 72 hours have lapsed, the Rust Bullet coating should be etched with Rust Bullet Metal Blast (simply spray it on, wait 15-30 minutes, either hose it off or wipe it off with warm water and a shop towel, and let dry completely), or lightly sanded with 100-150 grit sandpaper, before applying the topcoat, to ensure proper adhesion. This 72 hour period is decreased in areas with higher humidity levels. If a spray application of Rust Bullet has been accelerated by adding Rust Bullet® Rapid Fire Accelerator, a topcoat may be applied approximately one hour after the final coat of the accelerated Rust Bullet coating has been applied.
