Yeah i bought one of those pinwheel gizmo's, the guy selling it was an artist and made it look easy, to be honest I really havn't practiced with it much since I got the brushes, i did try it and I wasn't happy, the wheel ended up sliding instead of rolling, i'll stick to practicing with the brushes. another pinstriper that did 1 of my bikes pinstriped on the base coat, PPG, prior to my clear coating and said to use a little of the same reducer for the clear coat in the striping paint, which he did, and it's been 10 years since and still looks great.
