SPI (Southern Polyurethanes, Inc.) makes a couple of very nice clear coats that lay down like water, their Universal clear is closer to a high solids than the price would suggest and while I haven't used any of it their Euro Clear gets rave reviews from those who have. Also, they have an non-catilized intercoat clear that knocks the socks off of SG100 if you're into doing artwork or multiple candy colors in an unmasked scheme.
