I figured I would pass along a connection I have for 2" Blue and Green tape
Tigertape Inc 304-472-1414 Ask for Lee,
Mention Carl From Classic Marble Restoration in Broomall Pa.
I have purchased this for years and find it good to use and not as pricy as buying it from Home depot, Lowes or your local paint store.
I'm pretty sure he will send out a sample for you to try.
I buy 3 cases at a time to cut down on running out and shipping charges
