Apply in single wet coats, allowing 5- 10-minutes flash at 75°F/23°C between coats. For normal build, apply 2-3 coats, depending on desired film build. For high build, we suggest 2 coats maximum. If three coats are applied, allow for overnight drying. Body filler may be applied 1 hour after a single coat of PS3201™ has been applied. Additional heat may be applied to speed curing and drying. Allow to cool before sanding. Brushable / Rollable Option: Mix according to directions. Note: The use of slower reducers will increase flow and leveling. Apply 1 even coat of PS3201™, making sure to cover the repair area completely into the featheredge. Before the 2nd coat is applied, allow a 10 minute flash between coats. Apply the 2nd coat within the previous coats outer edge. For best results, do not apply more than 3 coats. Primer can be intermixed to achieve various shades of gray.
