The tips that had not be filled yet were done today. I tried to be a bit more careful to try to skip one af the operations. We'll see the result tomorrow.

I spent two hours sanding the tips I had worked on last time. The color of the putty makes it easier to see the places already sanded and the low spots. I filled the low spots before a las sanding session with small grit paper.

I tested the "sandability" of the mixture applied yesterday and it seems easier to sand than the previous mixtures. So I applied some to the tips on the horizontal stabilizer and on the rudder.

I reassembled the rudder and the vertical stabilizer to see how the tips fit now that I have extended the one on the stab. It looks quite good just some sanding to do. The gap seems also to be correct.
I then begin putting on the finishing putty, the brown color is due to the phenolic microballoons which are supposed to be easy to sand. We'll see tomorrow after the epoxy has cured.

Sanding on the tips goes on. First the build-uo on the vertical stabilizer gets sanded. Then all the aother parts are lightly sanded before all get filled again with some finish putty.
