Just learned a new lesson.
Few weeks ago, I polished some aluminum headlight bezels in the garage. Looked great.
Took them out in the sun, and I saw tons of scratches that I couldn't see inside.
My garage is well-lit. I have 8 four-tube fixtures. four in the ceiling and four on the walls, but sunlight beats flourescent light for showing flaws.
Today, more polishing and back in the sun tomorrow.
