Q: Do I need to sand TPO before applying this primer?
A: No. For raw TPO surfaces, this primer adheres directly without sanding or scuffing. For used or OEM primed parts, light scuffing may improve adhesion.

Q: Can I topcoat immediately?
A: Once the primer is fully dry, typically 60 minutes at 72 F or 15 minutes at 130 F, you can topcoat with compatible base and clear systems.

Q: Which topcoat systems are compatible?
A: It is compatible with most urethane and polyester base and clear paint systems. Avoid catalyzed basecoats, single stage urethane, 2K primer surfacers, or 2K sealers as they may reduce adhesion.
