Yeh , we use el cheapo paper based application tape used in the vinyl sign industry or masking tape - we were told it couldnt possibly work (by one of the top USA based blasting "teachers" who shall remain nameless;) But it works a treat.
The problem is overblasting , IE you cant blast the stuff forever and a day before it wears thru , but it doesnt take a long time to know exactly when to stop (when you see the residue clear).
In a pinch there is another option , but it is not recommended.
Buy polymeric cast vinyl (very thin and flexible) which you can use to wrap over a compound surface (you can actually wrap a ball with the stuff with a hair dryer to heat it) and laser it , it releases Chlorine and this combines with moisture to form hydrochloric acid , both the gas and the acid are bad news for you and the laser but if you really need it , it works.

The paper tapes dont get mushy when lasering them , and cleaning after is a snap , you just wet the glass and all the tape comes off with a light rub.

Rodney,
Thanks for your tip. I will know tomorrow how well this Plasti Dip works. It worked pretty good the first time, but there were very minor flaws that I was not going to accept. ( If I won't accept them, my customer won't).
I'll let you know how it works out. If it doesn't I will try the tape idea.
This is my first job, and WHY!!!! does it have to be so frustrating. :)

Thanks

Rodney,

I thought he was talking about regular masking tape as we call it here. There are thousands of different tapes. With our experience with the cheep Masking tapes the adhesive became soft or gooey when lasered and the only method of cleaning was to use cleaners like Naptha Etc.
