Just another sanding session. I sanded the parts that now had four coats of smooth prime. Once again the Smooth Prime sands so nicely and leaves a smooth surface. It takes care of the pinholes very nicely. Large imperfections still need to be fixed with a filler but it fills in the smallre imperfections well.
I got the two wingtips and the rudder fairings sanded. Since I still had enough waning light I pulled out the high- build primer and gave them a coat. I will wet sand these before using the Eko-poxy primer on all the parts.
