So I am part of a Huge car club and I create and make my own Decals for my cars, it got the attention of the club president and now wants to use me as his source for the clubs decals. I have done decals and just used transfer tape from hobby lobby. I want to get some good stuff and a large amount. Since I am doing car decals mainly for windows or wherever they stick them what would be the best transfer tape for me to buy. club president wants to buy from me in bulk, and I use oracal 651 as my vinyl of choice. what will be best since they may sit and i will not be doing the applying for anyone.
