Usually, if the top coat is attacking the base coat, it is wrinkles, not scaley., though if it is still soft, that is possible. Not sure why he'd say you'd need to heat the surface first, since that will casue the solvent to flash off too fast, thus not allowing the paint to cure fully first and it will not bond properly to the primer.
As long as the surface is about 45 degrees or warmer, that sould be fine. What do the directions on the can say?
Most clear-coat application is made after about 30 to 45 minutes after spraying the base colour, since all that is necessary is a flash-off of the base solvent, which allows the clear to bond to it rather than sit on top as it would with the base coat drying first.
Also, check on the lable, you stated previously that it was a base & clear mixed in the colour coat you are using. Some of those are not made to have a clear coat put over them later, as they are different materials. The mixed colour could be an acrylic enamyl base, while the clear could be urethane based, which will cause the reaction you describe, in both lack of drying and bonding.
