I shot the Eastwood single stage urethane gloss on my 51. Kade (grandson) said he wanted it shiny black, which pretty much meant it had to be shiny black.
You are correct, black will show every imperfection. But like you, I wasn't doing a show truck, so I figured it's gonna have it some imperfections down the road anyway.
Single stage urethane, for me anyway, was very user-friendly. If I remember (this was about 4 years ago), it took me right at 2 gallons.
