I just did pinbot with pimp stencils. You certainly need to hustle lifting the stencils and sometimes you need three hands when pulling up the pieces. I too put down too much paint, ended up with paint spider lines to clean up. BEST ADVICE, let it dry before attempting touch up.
All in all it came out fairly nice. Of course Im probably pushing 50 repaints. Gottlieb Wedgeheads are so mush easier.
When I want the fussy edge effect I'll use home made oil board stencils. Diamond Jack is one I did with oil board
I got to work on my webbing...
