Other - Is ordering GBL 99.9% online to remove paint illegal?

[tenakm]

This may sound like a completely naive question. But, my understanding is that GHB is of course illegal; but is GBL is legal (if you order it to remove paint)? Many years ago, I didn’t even think twice about it to use GBL to clean hard to remove paints stains or even cleaning my car's wheels with it.

In theory, under what conditions (and countries) does a person legally buy GBL from a website that sells it for legitimate purposes without getting any hassle?
