Brief Description: Countersinking VS spar doubler and scuffing ribs
Counter-sunk VS-808PP doubler, and began scuffing ribs for priming. I used Rust-Oleum Self-Etching primier on the HS understructure, but I found Rust-Oleum Professional Aluminum Primer at Lowes and tried it on scrap metal. Seems very durable, maybe much more durable than the Self-Etching primer. Going to test and research a bit more.
