Nearly lost a $1,800 insurance job over a fisheye I could not see
Was blocking out a rear quarter on a silver Camry at my bay in Mesa and the paint looked dead flat under my shop lights, but the adjuster's photo caught a fisheye cluster the size of a quarter. Turns out my air line had a tiny moisture pocket and my inline filter was shot, so I swapped it and ran a 12 inch test panel before touching the car again. Grabbed a $9 handheld LED from the hardware store and now I scan every panel with it at a low angle before I call a job done. Anybody else get burned by lighting instead of technique? I want to know what angle you check with.
Learned this lesson with my truck too. Washed it in the driveway at dusk and it looked showroom clean. Sun hit it next morning and I could see every swirl and water spot I missed. Same thing with my bathroom mirror, looks fine till sunlight comes through the window at a weird angle and suddenly there's toothpaste spray everywhere. We trust whatever light we happen to be standing in and call it good. Then a different angle shows us what was there the whole time. Good move on that nine dollar light, cheap way to catch stuff before it costs you.
