I'm just curious, but is there any particular reason why you want to start with enamel paints? or specifically krylon enamels??
ring up these hobby shops and try your luck there first.
Also, correct me if im wrong but games workshop only sell acrylic paints which can not be painted over enamels unless you apply a sealer afterwards to stop the paint from rubbing off...
its something to do with how oil (enamel) floats on water (acrylic) etc...
