RE: Post pictures of your RACERS!
This is the tape that I used on my first attempt at checkerboards, I would say that they came out "ok" but the poor job was not the tapes fault. I will use this stuff on my next project and will just pay more attention to making sure the tape is pushed down everywhere. You can get it at any Ace Hardware or Home Depot, its nothing special just regular ole' blue masking tape.
