No realy, this is bad, so I had it all clecod down with proseal to a 1"X3" 1/4 wall alluminum box 6 feet long, removed, placed every other rivet clecoed back down inbetween rivets, ( do you see where I am going with this )started with backrivet set, setting rivets half way down, go back to fully set and was not getting my width, go to remove and I magicly sheered the the rivet heads and pushed them into the holes I drilled into the box alluminum, ruined the skin. total nut head mistake, only 150.00 for new skins and stiffners but G wiz.
