Mike,
I have changed my preference for clear coats so many times in the past years I've lost track of half of them. With the loss of a decent supply of enamels I've concentrated on Tamiya Acrylics and later started using their gloss, semi gloss, and flat clears however I use their R-20 Thinner as opposed to their lacquer version to preclude decal damage with overcoats. I've found that a mix of about 70/30 of the Semi Gloss and Flat suitably thinned provides a nice semi Gloss final top coat. It also "blends" well with brush touch ups when required. I still use Future as a gloss coat before decaling however the Gloss Clear works well also.
Cheers,
Lance
