I want to do a clear coat over the hole cab, but not sure what to use ?
The blue paint I used was Enamel, the red is acrylic paint and for some of the fine black, I ended up using a oil based fine black marker.
What type of clear is going to be ok with everything I've used ? Enamel maybe ?

Generally you dont want to spray acrylic lacquers over acrylic enamels (to be term correct) as the thinners in the lacquers will damage/react with the enamel underneath (assuming not fully cured). Enamel is softer by comparison. You can get clear coat in enamel but i dont think you would want to risk it. These clears tend to yellow over time and enamel isnt the best for sanding back should you have to for some reason (such as  a run etc).

Personally, i would consider clear coating it with a 2 pack clear (acrylic urethane) but you would want to replicate what you have done on a test piece of wood or plastic before you do it to the cabinet. Thats my take on it.
