RE: How to repair the plastic outer skin of the Tufskin build ?
Ooops, 0.4 mm, you're right ! I made the mistake because it seems thicker than that.
Dealing with the color isn't so much of an issue as the original board is white. But it's true too that this no longer applies to the bottom and (thick) rails of the board : after one year of use, it's all tending to get yellow, except for where the tiki logo is. Despite permanent storage in a closed trail (ie sun exposure occured only during the 30-like sessions the board has).
If others know how to mix the plastic skin with other materials, thanks for sharing your views as Lampi kindly did.
