Why would using a squeegee prove I am professional or otherwise...I have this year started wfp from the off and about 20 years ago I did a 'spot' of window cleaning using blade & scrim...
It is just another method to do the same job...you know foot, bicycle, car, truck, plane, boat..... it is just another tool in the toolbox...
As for professionalism or taking more pride or not...does that not come down to the individual not whether it is trad or wfp.
Alot of the statements and arguments here are just from the playground and only serve to show that some thought process's are flawed.
