For all members in South Wales. UK, I have found a good company that can powdercoat chainsaw parts as well as other items such as car wheels
They have all the RAL colours for Stihl but i'm not sure of other brands.
I was quoted £80 to do all the parts including the front handle of a Stihl 041 Farmboss.
They dont have a website but they can be found on Facebook
The company is called
PUKKA POWDERCOATING
