One of many sanding sessions, been using 320 grit wet for primer and 400 grit wet for topcoat...
I had overall better luck avoiding orange peel on final topcoat this time, by reducing mixture 40-50%. I also made sure to visibily flow the paint on. The down side, due to the thinner mixture, I had lots of runs occuring on the near vertical areas, such as LE/TE spars when the wing was laid horizontal. I quickly cleaned them up with a clean wet sponge, with only minimal negative effect. Forget about spraying wings vertical on the stand, as runs occured galore. So had to spray horizontal, which of course set up more horizontal area for crap to rain down on during curing process. I still much prefer final product: nice smooth wet finish. Think I've got a method now to get reproducible results. On to the left wing....
