Put in oven @ 350° for 10 to 15 min. WARNING ; Make sure your wife is gone (hindsight being 20/20) ! Even oil from your fingers, can cause a lack of adhesion ,not immediately, but it will separate as it cures over time.
Edit: This is in preparation for wrinkle (crinkle) paint, NOT for curing sealants !
