Wed Feb 20 17:54:02 EST 2019

My Dad told me long ago that a platen can be softened by sandblasting. It does not hurt the platen otherwise.

typewriter platens. All these rubber dressings have some really 
foul smelling solvent in them. The Fedron worked for curing a 
platen that was very slick. I've also used belt dressing, seems 
like much the same stuff. Again, once the rubber has hardened up 
and started to crack or rot there is no treatment that will save it.
    The J.J. Short company recovers typewriter platens, I 
suspect they do Teletype machines too. An e-mail would find out 
their practice with this. They have a very good reputation among 
typewriter collectors.
