First of al thanks for letting me try this canaubawax ,I have tried it on my Harley Benton HBL400CS which I bought from you at Thomann in 2012 ,it had some small scratches on the back and side ,and by using this wax ,they almost disappeared ,also on other guitars did his work in a fine way ,so very pleased whit it ,and I would probably buy it in the near future from you guys ,a very good product ,does what you may expect it to do ,just follow the instructions for the right result ,( don't expect wonders )an old guitar has also got its charmes (it doesn't repaint you instrument) it cleans and fil small scratches ,but you have to keep you're instruments in shape ,it doesn't do it by itself ,.
