Is this a defect in the frame?
As I was giving the frame a nice wipe-down I realized a few weird dots behind the seatstay part of the frame. Is this considered a defect? Or nothing I should worry about?
Am I being OCD?

porosity in the TiG weld
if you see something that looks like a crack in the paint, I would worry - if not, it's probably fine and limited to the
"reinforcement" (weld build-up)

The paint on my raleigh looked like that at the same joints until I striped it and smoothed out the brazing with a file. Nothing to worry about, seems to just be cosmetics.

That looks like fish eyes to me. When you spray paint something and a stubborn little spot appears that won't go away. Maybe the scientist types in here can explain it.

I would agree doesn't look like something to worry about. More a combinatation of less than ideal finish on the weld and paint I have seen a lot of high end aluminium frames from the late 80's early 90's that look worse.
