Most anti-graffiti coatings don't make things "paint proof". They prevent the paint from bonding with the wall surface, so they remain easy to clean off.

The few that are hydrophobic and oleophobic can be expensive to buy and complicated to apply.

Yeah I was going to say "maybe it doesn't react to dot 3 break fluid, or etch like chemicals."

That dot 3 leaves a ghost when you add it to the ink mix that eats regular water based paints. Etch would get in good with glass.

Most of the anti Graffitti coating I see is virtually useless. It does make it easier to clean off but then the coating itself wears of through the cleaning process.

Yep.

There's cheaper stuff that does that. The advantage is that it's cheap, and basically applies like paint.

There's more expensive stuff that is more permanent, and allows for easier cleaning.

Then there's spectacularly expensive stuff that's like applying teflon/ceramic to surfaces. Paints and other stuff won't stick. But it can take weeks to prepare the surface, apply the chemicals, and then make sure it all cures properly.
