    I have use of a huge 8' x 10' heated indoor spa with an insulated roll-up cover:

    https://www.canhottub.com/classic-covers/

    Unfortunately the inner cover (foam insulation sandwiched between vinyl - I think) is deteriorating dropping very small black plastic flakes. Look like pepper flakes. I complained to the manufacturer who says tough s**t - must be chemical deterioration from improper chemicals in the spa (which I highly doubt). A replacement insulated liner runs about $700.

    Is there a flexible plastic/vinyl sealer I can use on this cover material?

    I believe I can cover the inner liner with mylar using 3M 77 adhesive but it would be nice to just coat it instead.

    You would want a chlorine bound plastic sealer that is flexible.
    I know of no such product, and even if one were found, getting it to bond with your cover would be another issue.
    I suspect that the cover is not made of vinyl, even if it is advertised as such. I have never seen PVC deteriorate in that situation unless mold is growing on it.
    If PVC cement will soften the material you have, scuff it up with a scotch pad and glue a piece of real PCV vinyl to the underside.

    Yeah, thought I might try Flexseal. The cover lasted a full year before it began to flake.

    If it works as advertised, you might be back in business, hopefully no mold.

    No mold! Dimensions are 96" by 144".

    I was thinking of adding a layer of polyester (PET or PETE) film using 3M 77 spray adhesive. I tried a small spot and it does seem to stick well. One question though is the weight of PET. 0.005" is reasonably priced but no more than 40" wide. Still I don't know if I could handle any material a full 96" wide.

    Solved the problem - for now. I posted a bad review for the company and now they want to send me a free replacement spa cover provided I remove the review. I agreed - once I have the replacement in hand.
