Bob Kent does but I haven't seen him for a while. Steve Stemmler from another forum did and he likes it. I may give it a whirl as well. I have a couple of bottles of Gibson Guitar polish which has lasted me for years and I use Fast Fret for my fingerboards which have lasted along time as well.

I've used it over the years and its great. I seem to swap between products (given as presents), but use either the Dr Dux or Dunlop's guitar cleaning package.

I have a bottle of Gibson and Martin polish that I have had for a while. I usually clean my guitars when I change strings and it seems that my polish last for a long time - and I mean long. I think I will buy a bottle and check it out.

I've used different brands of polish and string cleaner over the years...Bob Kent started a sub-forum on FB for Dr Duck users, so I tried it. Good stuff....
