Restore windshield seal or replace?

Project: '65 Coronet 440 2dr hdtp
Both the windshield and back glass seals are flexible and not weather-cracked. That being said, the car did sit outside for many years. My glass-installation guy said that he could "make them work" if I cleaned them up real good.
The car is getting a quality paint job done on it, and I would normally replace rubber parts without a second thought. I would hate for a good piece of glass to get ruined on the install because I was too cheap to go with new seals.
Considering the price of new seals (~$100 each), I'm looking at Eastwood's rubber and vinyl restorer product for $19.99.
Has anyone out there in FBBO-land used this product, or could recommend a similar one?
Also, what quality are repro seals? If they fit the way aftermarket body panels do, I'll save my money.
All thoughts welcomed, thanks!

If its not cracked or dry rotted, restore. I restored my hood to cowl, hood to radiator, radiator mat that goes under the radiator, and the suspension bump stops by using '00' steel wool with some dawn dish soap. Once clean, the rubber was plyable, shinny, and then I treated it with some aerospace 303.

The seals in my abodies are fine after reusing them.
Clean the channel as necessary.
I put polyurethane roof sealant (black at Lowes' Depot) in the channel, put the seal in and then shoehorn the glass in with multiple rounded, smoothed putty knives.
Clean the mess off with mineral spirits.
By doing this I've actually later replaced the windshield without the rubber coming out.
It's glued in and won't ever leak.
Two things what will sound pretty shade tree, but it works.
Your rubber probably will have shrunk up after being out of the car.
Stretch it between two post with a come a long till you get ready to put it in.
And take the sharp edges off of the glass will help get it in the rubber.
I use a hand held belt sander.
Windshields are pretty tough but don't twist it.

If it was me I would opt for the new gaskets.Fresh paint and use a 40 plus year old gasket?The new gaskets are fine.

Thanks to each of you for your input. I've decided to prep the seals as advised and let my glass guy decide whether they are good enough to re-use.

I've used many glass weatherstrips/seals over the years, not only on Mopars, but other makes as well. Never a problem, usually Steele or Soffseal. I've always preferred to use new seals. Why not buy the new seals & compare them hand-in-hand ? You can then see if any shrinkage, deformation,etc may cause issues. If the old seals are good, return the new ones.
