Trying to pull off the enclosure so I can get some new eisenglass. Can't get 2 of the zippers to move. Tried some pb blaster and some dish soap but they won't budge. Ideas?

Try some WD? Spray some into the cap and "paint" on both sides with a brush?

wasn't sure where this was going.....

You need outriggers before new eisenglass! Try some of the on the market polishes, I have use the Mequiars Premium Vinyl&Rubber Protectant with good results.

Sounds like they are metal zippers, got to give them some sort of shock to jar them free of the corrosion locking them. Along with the p-oil.

Give 210 Aqua-View a shot at the glass first, may clean them up good enough

If I remember those are the big black plastic Zippers, I'll guess at loosen up the curtain where possible, grab the zip with plyer, shake the hell out of It After all the lubes mentioned above

Took the boat clammin Sunday, I think that's a wrap for me,,,
Winter sucks

If they are metal zippers then I'd try spraying with Saltex and let them sit for an hour then pour some hot water on them. This has worked for me with the zippers on my fly satchel that I use in the salt. Ron

I tried every product for months....
