Flexible coating/sealant materials?

Inertially

What coatings/materials are flexible, long-lasting?

Works even when applied in thin (<1mm) layers.
Won't flake, crumb or crack.
Acceptable abrasion resistance.

Something like Silicone Gasket Maker (Auto RTV) or plastidip (Synthetic Rubber Coating)

I heard caulking compounds falls apart/crumbs.

Except, maybe cheaper.

Rubber roof coating?
Polyurethane?

Some type foam-ish rubber?

Just Bill

What are your trying to coat, and what result are you expecting?? There are coatings that do all that, but many have specific applications.

Inertially

A sheet of paper or tape.

Result - a long lasting, flexible, maybe somewhat elastic/stretchy (just not brittle, durable, something won't fall apart or crumble), abrasion resistant durable pad/sheet.

What coatings do all that?

Stuff like Silicone II is really weak and crumbles into a mess.

An office supply store can laminate a sheet of paper for you. That will do all the things you've mentioned.

Inertially

It's not elastic or soft enough or thick enough and the coefficient of friction is too low, it needs to be grippy/tractional.

what exactly are you trying to do?

Inertially

Make friction response inserts for a yoyo, on toy yoyos, the when the yoyo is pulled or binded (when there is string slack, when the response pad and string make contact.), the string grips with the grippy response (traction) and the spinning yoyo rolls up the string and returns to the hand..

Point is to make (my own, do-it-..myself) something and figure out what works well.

Not to buy something specifically for it that already exists, i wouldn't ask on DIY forum if I wanted to do that.
