I did not succeed after several weeks of research to find a carrier who agrees to ship here in Quebec gray Stihl paint or Ford light gray aerosol. It's really a problem for me, I can not find any painting that could match for my Stihl
If you can't get it in a spray can, buy a cheap paint gun and get some custom mixed at a shop that sells automotive paint. Paint made for cars is going to be resistant to fuel and oil.
You can bring them a saw that has the right color paint and then can match it, too.
