Hi all My first post on here, lets see how this goes! I have a customer who has horrible sticky leaded glass, almost impossible to do traditionally without leaving smears. Changed her over to the wfp which brings the windows up brilliantly, and I get the job done in half the time! However... found out from somebody else that "she's not too keen on this new system and wants to go back to traditional" Really frustrating!! Anybody else had similar experiences? How did you deal with it? Thanks guys!
