Found Vipaseal Gloss quite easy to use although I still found it does still crease a bit.
Using the squidgee helps a lot.
After lots of trialling, Melissa from Vipaseal, has come up with the best book covering product ever. It is easy to use, you can reposition it while covering a book, and it feels good. My helpers who I have just taught to cover books and my old hands at covering , all love it and won't use anything else. Bubbles are a thing of the past in our library.
The Vipaseal Gloss is so easy to work with and best of all no wrestling with bubbles which is wonderful. Will be purchasing lots more!
Nice looking finish and good adheres well to the book edges. Easy to work with. Time will tell if it is durable.
