AHHHH--BRILLIANT. I should have asked if anyone has an improved method to add flocking first. Of course that's going to be much easier since you don't have to have sticky material all around the inside to get it to work. THANKS--I'm definitely not going to forget that.
You know, I probably wouldn't have appreciated the advice as much unless I went through all of the hassles in using the totally sticky flock backing. I'll tell you it was very time consuming to get it in there towards the inside by the lens.
OH--and notice in the pics how there are reflections on the outside of the barrel but none on the inside--so that does provide a comparison of before and after.
