try www.luckymodel.com right now they show that they have the jar of mr. surfacer 500 and it's in stock.
Given Mr Surfacer is a flammable liquid it cannot be mailed. The day will come when those vendors shipping these items illegally will feel the wrath of the postal inspectors in the destination countries. All it takes is one little tiny weeny accident or a package being damaged and its contents exposed.
Globally the postal services are tightening their regulations to be cohesive with each other to be safer.
