On to scuffing the items I wanted to prime, as well as deburring, edge finishing all the pieces needed to assemble the horizontal stabilizers. I chose to selectively prime my pieces based on items I thought would need the most protection and the items I knew I could keep the Alclad intact, I left it alone, because alclad is superior. It's also helpful in weight savings and money savings. This took a couple days to complete fully, I scuffed ribs, used acetone for cleaning and then primed with SEM EZ Coat. The edges of the skin went really quickly using a vixen file and then a combination of the sauviv (sp?) edge tool and scotchbrite pad.
