This Mod corrects the, in my eyes too extreme, grungy Look for the Microsoft DHC-2 Beaver default liveries or any livery without its own COMB Files.
Just drag and drop the downloaded folder in to you community folder or add it to the community folder with your preferred Mod Manager.
To see what this mod does, just look at the two attached screenshots of a default Livery.
This mod does not clean the look completely like it would be a new plane. it just makes the used look look better in my eyes;)
Try it. If you like it, keep it. If you dont like it remove it from your community folder and you habe your default look back.
