I sprayed two full coats on a fiberglass hood last night and kept the temps all night at around 65-70 using lamps. Today, it sat in the sun for about 4 hours until the temp dropped and panel temp quickly went down into the 50s. All in all, it was about 18 hours before the temp dropped on it below 65. I know it is supposed to be a minimum of 24 hours, but how do I know if it cured or not? I’m planning to block sand late this week to 600 before a sealer coat and then base/clear.
