I have my 72 Corvette with 2 coats of Featherfill over the whole car. I am going to block it with 220 this week and hope to get it in epoxy by the end of the week. I won't be able to get back to the car until the beginning of June. Then I was going to wetsand the car with 400 and apply the base and then clear. Can I leave the car in epoxy for the couple of weeks without any problems when I spray the base.
