i know you are all probably fed up with my stupid questions but here i go with another one
we have all had bird s**t on windows that needed a lot of work with a blade to remove them,if using wfp would they come off or would i need to go up a ladder with a blade?
btw i was in cleantech 6 months ago and mike was explaining how good wfp is ,my comments to him were that i would never need or use wfp,now look at me im going to be using it within a month!
