Sheltie shopper 5 I wanted to test this new topper for a glass coating as it seems to be following the trend of US and European companies offering silica infused sealants/toppers here in Japan. It says it is to accompany their glass coating, so it is similar in design to CarPro Reload, and the results were very impressive. I did a decontamination wash with iron remover and a full detail (no polishing) on my car, which had a glass coating applied 1 year ago. The shine was very good and the beading and hydrophobic properties have lasted over 1 month. I applied by spraying onto a microfiber disk applicator, not directly, and massaged into the paint using a cross hatch method, then let it haze and buffed off. A double application is best I think. For only ¥2000 it is great cost performance (コスパすごい!) to get the most out of your ceramic/glass coating, or just as a sealant if you don't have a coating. Very deep shine and some scratch covering on dark paint. I bought another bottle to keep in stock.
