i use gg3 now after 16 years of fairy!how you can go back to fairy is beyond me!

gg3 is miles better hardly any suds or bleed to detail after squeegying.youll be quicker and do a better job!!windows seem to sparkle GLEAM better than fairy!also fairy is a bugger to clean the suds up esp on dark plastic frames!! :

GG3 is harder to see when trad poling but does any EXCELLENT job with no smears or smudges!

i use twice the recommended dose in my bucket(gives it better slide)and ill be ordering the 3.8 litre tub when i next need some.its very concentrated so i dont think itll work out much more than fairy.
ITS WORTH IT IMO.it does a much better professional job!!
