I am not a fan of the Alclad primer and neither are some friends of mine. we all experienced issues with the Alclad primer not drying for days. I have had very good success with using a gray primer and then polishing the heck out of it to get a super smooth finish. I have also used regular black as a base and then polishing that for the specific colors like chrome. Best practice I've had is polishing the surface with up to 12,000 grit materials. Also, make sure the surface is extremely clean along with smooth. The Alclad will really pick up any scratch, dust, etc.
Recommend a little experimentation, before committing to an expensive kit. Good Luck.
