Sliding Window Parts

[sundown]

I have a "new to me" 20 year old pilot house sailboat. The sliding windows are pretty much frozen in place by the salt encrusted "felt" channel liner.
I have tried in vain soaking the salt from liner in fresh water (Though living on the "Wet Coast" of Canada there is no shortage of rain).
I would welcome suggestions of how to get these sliding windows functioning again.
For what it is worth I am able to get them to open an inch or two.

Miamicorp.com carries window channel parts. If you can move them an inch soak them down with silicone and just keep working them. Fwiw

Silicone ?! Do you mean something like the product that West Marine carries called "Capt Tully's Creeping Crack Filler"?
Thanks for the lead on the window channel supplier - I have 'book marked' them as potential solution.

I think he means silicone lubricant spray.

You might try some WD-40. That stuff is amazing
