Royal Mail prohibits the sending of caustics, which includes 'corrosive paints' and rust removers. It also prohibits sending any paints or varnishes. Although the actual words 'paint stripper' don't feature I reckon it would be most unlikely that this stuff could be sent by post. Just imagine the problems it could cause if the can were to be punctured...
That said, there are any number of courier services which
would be willing to carry such items.
