Yes, plasticizing makes paint sticky, more so if applied on the side the print is.

It does fade away over time(mostly, at least). I'd guess regular cleaning using soapy water helps too.

I think that seller from my country does ship internationally. Much better deal than what the russian offers, even with taxes and expensive shipping included.

But again, imports... Shame this seems to be the only reliable way to get it in so many places.
