Hi Andy,been doing it for years.for outside stuff also.
I used to do a hotel where I needed 4 different sized
`custom cut`channels that fitted each window.Don`t
Do it at all now,outside I WFP and inside because
Of the lack of nicotine ( smoking regs) I just `whip`
Over em`with a scrim or microfiber.
The big advantage with straight pulls with your squeegee
Doing this type of work is your rubbers last a lot longer
.helluva site longer
