What did I do to my vinyl?

Anyone seen this happen before? Last week was fine, took the cover off this week and found this.

I used 303 like I always do once a month. It only happened on the colored vinyl on the back. All white vinyl and other colored vinyl is fine. It isn't brittle, not spreading as far as I can tell.

No sunscreen on it that I know of, no other chemicals other than 303 that I know of.

Any ideas?

I'm planning on using gorilla repair tape for now until I can afford to replace it.

May have answered my own question - has anyone ever seen hail damage look like this? This is the only part where the cover touches, so it would have been nice and toasty, and I did notice a decent storm pass over my storage place last week.

WOW! Must have been quite a hail storm!

Yup . Hail damage was what I was going to say. Happened to my friend a couple years back. Insurance company will replace
