In response to your suggestion, I understand about shooting the white laquer first then the red enamel. what I don't understand is the dry time you advised.
Laquer flashes off, then dries almost immediately, while enamel dries slowly unless a hardener is added.
Unless I misread, your post says to let the laquer dry overnight, then shoot the enamel, let it flash for 20 minutes, then wipe off the embossing with mineral spirits.
My question is how do you avoid taking off the enamel you want to leave on the lower suface while removing it off the embossing since all the red paint is still wet after 20 minutes?
