Cabinet Finishing - Protecting the Paint

[dingorob]

I would like some advice on how to protect the paint / finish on my cabinet I am building.

The cabinet was restored from an old junker I bought cheap.  I sanded it down, put a gray latex primer on it, and last weekend sprayed it black. The black looks good with the semigloss finish although it turned out a little more matte but thats fine. The problem is it feels very rough to the touch and marks very easily.

What do you recommend to finish the wood with. I have two things ideas. One is a latex clearcoat, and the other is a furniture wax.  Can furniture wax work on latex paint?

Should I wetsand the latex down to be smooth, and then clear coat it or should I clear coat it and then wetsand the clear coat?  I am also conscerned that it will be too shiny, but I would like the finish to looks sharp, contrasty, resistent to scratchs and fingerprints and accidental beer spills :p

Thanks,
Robin

I am planning on using Mixwax clear finish on my painted cabinet (not sure if I'm going to use mdf or plywood).  I am anticipating putting 5 thin coats on the thing for maximum protection over 2 or 3 coats of light pink paint.  I'd love to hear other people's thoughts if there is a better solution...
