In this Instructable, I will show you how to mask off a particular area prior to sandblasting to protect it, in this case I will be masking off the emblem on a bike frame. This type of masking is ideal for aggressive sandblasting at a close range for long periods of time.
Step 1: Cover Area With Vinyl
Cover the area you would like to protect from sandblasting with vinyl (with adhesive on one side). Use enough vinyl that it covers more than the area you wish to mask.
