What type of adhesive should be used to attach the replacement mirrors to the replacement masonite boards in the mirror holder frames? These are at the back sides of the m100c mechanism compartment. I don't want the adhesive to "bleed through" and discolor the mirrors.
Thanks,
Steve

Steve,
The last one I did, that I still look at, some 12 years later, I used some general "contact" cement, such as "Barge" or Ducco", brand. Still looks fine-- Ron Rich
