[TIG] sticky rollers

In the early days San Lab did look at giving a dollar for the old ptr's
and re-using them but this turned out to be not cost effective ...  The
sticky tape does not take off the surface but some tape has a risk of
leaving its glue on the ptr. This is not good for the film. There is one
specific tape that has been proved ok, I'll find out the name and let
everyone know. The ptr's have a microscopic groove machined into them.
Its this that makes them so effective ..  so skimming them would remove
this property and render them useless.
Hope this helps

I have always washed my PTRs to clean them, as i was told by various
engineers and colourists that using sticky tape to clean the dirt from
their surfaces also had the undesirable side effect of essentially
removing the rollers 'sticky' qualities and shortening their useable
life. Which neatly segways into the following question. does anybody
know where your can get old PTRs reconditioned and is this a worth while
procedure, i've heard it can be done, but that the 'reskimmed' rollers
have a shorter life span then brand new ones, and can 'go off' quickly.
