I also love enamels, but would caution you not to just use any paint thinner. There is some synthetic stuff being sold these days in hardware stores that is just crap. If you go with hardware store stuff rather than hobby shop thinner, hold out for something that specifically says mineral spirits or turpentine.
The synthetic stuff I am talking about is not clear, it is cloudy and has undissolved solids in it, but it is sold in opaque bottles so you cannot see it till you buy it and open it. That is why you want real mineral spirits.
