I use Grafmatic film holder and the biggest problem is, the light trap felt. The felt wool comes loose and settles on the film leaving a mar k. I think because of age the felt is disintegrating and falling apart. I opened the whole thing and cleaned it but, i think i have to replace it sometime very soon. Now, i don't have a faintest of clue what to replace the present light tra p felt with. I would really appreciate if someone help me restore/replace the li ght trap.
Thanks in advance
