How fast can I sand and get to primer or topcoat?

Platinum Plus Glaze is engineered for quick sanding and short work cycles. Under typical conditions you can begin sanding in about 15 minutes, depending on temperature, film thickness and catalyst amount. The fast turnaround reduces overall repair time so panels can move to primer or topcoat sooner.
