Seal and Prime Horizontal Stabilizer

I decided to start with the horizontal stabilizer, since the bottom of it is not likely to be seen very closely. The first layer of sealer (the gray-colored EcoFill) is actually brushed on with a foam brush. This went okay, but when it was dry there were several chunks of foam embedded in the coat, and there were also several brush marks. It turns out that I should not have brushed across the pinked edges of the finishing tapes. Instead, I should have brushed down the edges. Also, I waited too long before "tipping" the brush strokes to smooth them out. I should have either tipped them earlier, or just simply left them alone.

After brushing comes spraying. I'm using a different gun than what the factory recommends in their videos. As a result, I had to play with the settings a little bit in order to get it to come out right. I kept getting a finish that resembled sandpaper. (I'm certain that the high Las Vegas temparatures had something to do with that, too!)

After the gray EcoFill comes the while EcoPrime. Technically, EcoPrime isn't required. However, I decided to use it for several reasons. First, the gray EcoFill is somewhat tacky (even after drying). As a result, even if I managed to keep the parts from touching each other, they'd inevitably pick up dust and dirt from the shop. The EcoPrime is less rubbery and more like normal primer. It sands really easily (and I mean beautifully). It also has a harder finish and is less likely to pick up dirt, and is also less likely to stick to another primed part.

The second reason for using the white EcoPrime is that the colors I'm planning on using come out brighter when sprayed over a white object instead of a gray object. If I was going to paint the airplane white, then I might not have bothered with the EcoPrime.

Total Time: 17.0 hrs.
