German ID number on an eFoil

Hi all
In Germany eFoils have to be registered and own a ID.
This ID should brought on in letters , 10 cm hight, on the right and left side of the foil.

How did you do this ??
A sticker will not hold in place. paintjob might destroy the material and its not easy to find space.
my plan: Work with stencils and spray with rubbercolor like “PlastiDIP”.
I saw other threads here in the forums but the signs have not the needet size … so it is stricty as driving with no valid ID.

Thanks
Tom

We use stickers from a plotter since years without any problems on carbon fiber and fiberglas boards. Inflatables are a little bit more tricky, but should be also good for one season.

Sounds good but I have a Waydoo … no way with stickers.
