Hi,
Have all the small parts sanded after applying the sanding sealer, tail halves,elevators,ailerons and the rudder. Wings awaiting further assembly work.
I have glassed (0.5 to 0.75 oz) models in the past and this stuff takes more sanding - to my surprise !!
The 0.3oz seems very different to the 0.2oz in this regard. It does take a lot more dope to seal to begin with.
Anyway I am able to use sharp 400gt wet paper to flat this. Even with the 400gt I had a lot of sanding on these parts and using considerable pressure.
They are finish sanded with 600gt.
The 0.3oz carbon has a big advantage over glass for this process - you can see exactly what is happening !!

Matt, The second pic is both tail halves c/w elevators on the scales - not to bad but weight is up some !??. The third is one of yours taken from your 'covering balsa with carbon veil' thread for reference.
