I have some of the 3m silver awaiting use.
When I build a lugged frame commuter, I have been struggling with the idea of coating the WHOLE frame in this material. Basically, I could cover all of the tubing, and paint the lugs a contrasting color, and HOPEFULLY, no one would be the wiser during the day. Should be a fairly durable scratch resistant, and good looking finish. Should be better than a spray can job.
I've found some on ebay for a decent price.
