Started wfp back in 2002 and no one else around was doing it so had a hard time trying to sell it to customers but commercial were fine with it. Figured out how to wfp by trial and error, even how to fix a van in tank all the other wfp stuff to learn with no videos on you tube or the clean it up forum haha.
great post . same here I had been trad for 13 years , and went wfp in 2005, it took me a while to suss it out, and sell it to my customers .
like you say , there was no cleanitup, no you tube and no othe wfp guys around.
I started by just doing the upstairs with the pole , but after a few months was doing everything wfp.
its far easier to learn than trad with the right help.
my daughter picked it up within a few weeks .
When she started I explained how it works whilst showing her, I explained about the frames needing to be done , I explained about the dirt in the vents , and explained about first cleans . I also told her not to worry about speed , but to concentrate on quality, and always getting it right.
those first few weeks we went through water like it was going out of fashion. yes it was a little frustrating at first , but within about a month she was up to speed , and doing a thorough job.
the customers also gave great feed back.
