Hi Alan!
Thnak you for the comments and suggestions. I agree that on light colors, a darker panel line tends to stand out.
I use a micro marker (.05) from Michael's, in black. I once tried it in dark grey, and it was of course more subtle. Thta variety is harder to find, however. I tried the "highlight before paint" technique once, but my polishing routine used to create uneven finish.
Oh well... LOL
