This arguement pops up every now and then ......and will always!
My opinion.............
19 years traditional. Nearly 1 yr WFP.
Trad - lovely spotless finish! - Bloody hard work, bloody lugging LADDERS!!
WFP - easier, quicker, overall better service, earn more money - but LEAVES WINDOWS WET!!
Thats the bugg bearer with WFP - leaving the windows dripping wet!!!.
A bit like a baker puts a cake unbaked in the oven and it comes out lovely - he knows it will!!
99% of the time our windows dry of fine - but, especialy at first when we are learning, that one dries out with runs or spots and the customer rings up!!
It knocks your confidence!!
WFP is SOOO simple -
Brush and wash then RINCE well with PURE water = Dries out to a perfectly clean job!
It's the logistics of doing that that can make WFP more complicated!
