Any STD on removal of sound dempering material on 67Bs?
Was there a STD for the removal of all sound dempering material/charcoal gray pads from the internal structure of the fuselage of 67 337Bs and O-2A/B by FAA due to corrosion build up between the pads and aluminum skins or panels.

I have been asked by a 337 specialist to remove these from the side walls, top and from the floor of my AVM. This stuff has been glued pretty good for last 49 years and is giving hard time to come off by using lacquer thinner.....
