Did a test of Liquid Glass(polymer or acrylic type protectant similar to Klasse) vs. Klasse AIO. Liquid Glass is as good, if not better than Klasse AIO. Easy to apply, easier to remove than Klasse AIO, even after drying completely. Seemed to clean a little better also. Leaves a candy coated shine that is equal to if not better than Klasse. It definitely beads better than Klasse AIO after one application. It is sold locally at stores so it has another point going for it there. Also has a website with a FAQ and ways to contact the company unlike Klasse. I will need to try my Klasse Sealant Glaze on top of Liquid Glass so it doesn't go to waste. Liquid Glass is a great product that has been around for many years and I see no reason for them to change the formula.
