Great to hear you had such great success with this repair!

I have an older Japanese 'Scan that I replaced the foam on, as well as added teflon tape to the focuser a while back.

Mine's collimated quite well, and handles reasonably high power, though I usually only use it with a 32mm Plossl.

I 'made' my own PFT tape for the scope with teflon pipe wrap from the hardware store and double-sided scotch tape. Worked like a charm.

I love these scopes!
