I have quite a few leaded houses, and find WFP BRILLIANT for them.
Far, far easier and quicker than hand-bashing.
I also do a small hotel with many real old-leaded-windows. It used to take two of us two hours to hand-bash the exterior.
I can do it by myself in about 1 hour 20 minutes and still charge the same money. Some windows leak, some quite badly; but overall I think the job is better done by WFP than by hand. It's really fragile glass.
It's my best account and a nice little earner for the time it takes.
The only downside is that we have to handbash the interior every-other-month!
