Q: How many coats and when should I recoat?
A: Apply 2 to 3 thin coats to reach 6 to 7 mil dry film. Recoat when the prior coat is dry to the touch with slight finger drag; scuff if it has fully cured.

Q: Can I thin it and with what?
A: If thinning is needed, use POR-15 Solvent up to 5 percent. Clean tools with POR-15 Solvent before the coating cures.
