That's the reason I'd use tape - undo-ability. If I was going for permanent I'd use petroleum-based contact cement. It just feels better to me personally.
Just realized how old this thread is! There are certainly businesses with that attitude, don't like it go somewhere else. While it's entirely up to the business owners to be that way, I think it's good to be forewarned about it so if you need to do business you can go in with an accommodating attitude, sort of butter them up if you will...:)
As some may know I experimented with DIY sparkle wrap a while ago. It turned out well but was "open" on one side and wood-glued to the shells. Well I'm on the warpath again to make wraps out of hex glitter [flat] and crushed glass glitter [chunks]. This time it will be sandwiched between two layers of Dura-Lar, with acrylic gel medium as the bonding agent. [I've been doing some reading on Dura-Lar and what works bonding-wise]. The backing layer will have a coat of paint to enhance the look, as in the putty coloured base of Ludwig silver sparkle.
If it turns out well I'll post a thread on it here. I plan to sell it cheap tho I guess, given that it won't be "real", it'll be mainly for MIJ kits...except for one Club Date kit...mine. :)
