I have a project Pin, that I'd like to seal the paint job on. I recently repainted it without priming, so I'd like to try and protect the paint I applied. I have 2 different finishes of Polycrylic. On their own there's not enough to get several coats of the same type. I'd like to coat twice with the Glossy, and then a final coat or two of Satin. Has anyone done this? I'm trying to avoid buying another qt of the Satin, and I'd like to use what I have. Will it dry in Satin as long as I give it a good coat or two in a Satin Finish?
 
Whether or not you do a protective clearcoat should have nothing to do with if you primed and prepped it correctly.
 
The problem is, there weren't stencils for the body. I sanded it down and prepped it for repainting, but didn't prime it so I could use the artwork as a guide for the repainting. Am I wrong to assume that sealing the entire cab with a protective clearcoat isn't somehow protecting the paint against peeling or damage? Does it not bind to the paint and offer added strength? Anyway I wasn't really asking "if" I should do one.

Maybe, maybe not. The clear could bind to the paint, but the paint could still release from what's under it. It will help bind little flecks, like if you're sealing a peeling backglass, but for a painted cabinet, this wouldn't necessarily help. I did a lot of research and asked a lot of questions - should I clearcoat a pinball cabinet that I repaint and the majority of experienced restorers said no. I ended up spraying semi gloss latex from an HVLP gun. Here are some pics-

Since spraying isn't an option for me, I have to roll and apply the stuff by hand.

Update for anyone who cares. I mixed the two finishes: 2 initial coats of glossy, and 3 coats of satin. It worked fine, and the finish is Satin, and seems no different than if I had done 5 coats of just satin finish.
