This was recommended to me by the detailer who ceramic coated my motorcycle. It is very easy to use, you need to spray it onto the cloth you are using and not onto the panel. This helps to build up the product on the cloth and helps to get it in to difficult to reach areas (there are a few on a motorcycle), the level of finish remains amazing, with the depth of shine and water beading very good. I have used this about 5 or 6 times since the ceramic coating was done (2 months) and I still have more than half of the 250 ml bottle left, at the price this is very good value for money. It would be nice to know what or if the % of ceramic or SI02 is in the mix.
