it's good to know the product sells and the interest in it seems genuine! I am really interested in reading any real world experience comments or reviews. At the moment the blade is out of budget for my experiments but I am definitely am going to keep an eye on future developments. Thank you for your efforts.
EDIT: Isn't it strange? I have been looking high and low, but right after I posted this reply, I found some of the photos you had posted earlier - I did a search for photographs of coating blades - and found this thread: http://www.apug.org/forums/forum42/25972-foam-brush-paper-coating-question.html
