Back in the enamel days no way, now even with base coat it is best to not let the paint flash and dry between coats, the clear is the reason I can see taking your time but it sure don't need to flash to far, Just an old hillbilly doing this for 10+ years but have not painted for 10 years.. I guess I was taught to never let it close to drying at all.. I never rushed or needed to unless it was a long/big truck or car
