I used 505 for the first time on my Japanese Fan quilt. Great it worked well for me, however I did use it on the back and the front of the quilt, so one can went. I did reposition it. What I did find was because I was hand quilting it did move, so ended up having to smooth it out twice, thats how I managed to use a full can on one rather large quilt. However I did get excellent results with it.
