Dear #sewing people, I have this second hand bike bag and I assume it has some sort of vinyl sheet glued on the inside [Polyurethane coating], which is completely giving up. Regardless it is still waterproof but the flaking is really bad. Can I just... slap a new vinyl sheet on top ? Or would it be more reasonable to make a new lining ?
(I could scrape the whole coating out but I don't have it in me right now)
@just_chill that's probably a polyurethane coating that was applied as a liquid. This seems to happen to most pu-coated items after awhile, and it will eventually no longer be waterproof. You can re-apply a coating to the inside or apply a different coating to the outside. I like to wax the fabric in situations like these, but it's not safe on all synthetics.

@cathos sounds like the perfect link, thanks a lot :meow_sign_thx: I will probably go for a more environmentally friendly replacement eventually, but for now just a new lining to protect my stuff from the flakes.
