I've been using Zaino products for a few years on my bikes and cars. My brother gave me a kit of Crystal-Glo for Christmas so now I can compare the two. While the Crystal-Glo is nice, the finish from the Zaino is more slick. Things are less likely to stick to it. Both are easy to use but the Zaino just feels like more substantial. It smells better too. Neither are cheap but in the same price range. If you're a Crysta-Glo user and haven't tried Zaino products, I think you would be impressed with them. Just one man's opinion.
