Much better result. The harsh direct sun accentuates a golden brown that doesn't show in the house, it looks darker and closer to an ebony stain.
I did pick up a random orbital sander but have to say my trusty old Porter Cable 505 works much better. The 5" feels like a toy.
I would have liked to try stopping at 120 grit in order to soak up more stain but I am happy with 180.
I have never worked with DuraSeal Quick Coat Penetrating Finish before. It is a stain but includes filler and doesn't even need a finish coat. I will use one though, just haven't decided what to use yet.
My wife prefers the grain pattern on what I had planned for the bottom so these may be flipped before I install the Neutrik speakON Chassis Mount.
