[ATM] fix for turned up edge inside of rolled edge

[Mark Yama]

I would appreciate thoughts on this problem.  I am working a 26 in BVC mirror.  I had a rolled edge maybe 1.5 inches wide.  Eventually I reduced it to a 1/4 inch rolled strip by directing using a 8 inch tool just inside the extreme edge with accented pressure.  It took a long time to clean up the resultant roughness, perhaps because of the softness of the BVC.  However, I now see that I have about a 1/4 inch turned up zone just inside the rolled edge, which is itself about 1/4 inch wide.  I am resigned to just leaving the outer 1/4 inch as it is and masking off this part of the mirror.  But I would like to correct the turned up zone just next to it.  Now, might I just treat this as if it were a rolled up edge at the extreme edge of a mirror, and use a procedure like in Textura where you use a tool, overhanging the edge slightly, and exert pressure here?  Or would this lead to more problems.  Thanks for your thoughts.
