I dimpled and countersunk all of the ribs and spars for the vertical stabilizer tonight and got everything primed. Unfortunately, the digital scale I bought for mixing the primer and other chemicals came with a really crappy 9-volt battery that basically only worked for about 30 minutes when I mixed the primer for the horizontal stabilizer. Tonight, after midnight and right in the middle of mixing the primer, the battery died and I couldn’t find another 9-volt battery anywhere in the house. Fortunately, we live fairly close to a 7-Eleven, so I was able to run out and get a new battery before the epoxy primer started to cure and finish the priming.
I’m really liking the Stewart System EkoPoxy primer. It’s trivial to clean up and I’m very impressed with the durability on the horizontal stabilizer structure. It’s very hard to scratch, and it’s impervious to basically all chemicals. I really like the fact that it isn’t highly toxic like other epoxy primers, so a simple particle respirator is all you need to spray it.
