I also installed my ADAHRS but then that came to a stop when I realized the data cable I ordered from Dynon was WAY too long. So I sent it back for a shorter one. I'll finish that install when it arrives and will post about it then.

I prepped the plane by wiping it down with some acetone...very lightly so nothing soaked in. Then I lightly etched and alodined the aluminum and wiped it clean. I also prepped the shop for painting.
Tail number painted on!
I used a high build primer from Sherwin Williams. The normal automotive stuff. easy application and easy sanding. Here is a picture after the sanding. First I sanded with a block and 120grit. Then I switched to 180 in some of the low areas. Then 400 grit everywhere by hand. It gave it a nice smooth finish.
