Just wanted to compliment you on a sharp-lookin', simple , rideable byke. (as I suffer from making them too extreme or rather too absurd so as to be nearly unrideable, i.e. a kids frame made for 16" wheels but with a 3sp, 12" rear wheel ,27" front , no brakes and apehangers: wheelie city!) ANYWAY--
Metallic paint is really cool-For some nifty swirly effects, mix two different metallic colours, one oil-based, the other latex-based--the degree of stirring determines many things about the outcome-the fun is in experimenting with the unknown!
