Some none spectacular but very important work in preparation of tomorrows priming session.

The aluminum must be first prepared with silikon entferner (silikon and grease remover) and aceton.

It must then roughly scratched (carefully, not to remove too much of the alclad layer) with maroon scotchbritepads.

Tomorrow, just before priming, I'll have to do the silikon entferner again to finally prepare for priming.

I did all stiffeners of the left and right stabilo. These are difficult to maintain in the right group as we you have to remove all pen markings. I'll keep them in seperate batches by elevator and side. The H-pieces are problematic, they are all the same size.
I read you cannot keep the pen markings on as it is the first place where corrosion starts to form.

I also prepared E615PP, the cover plate and the two skins.
