While deburring the corners of a HS spar doubler, the deburring tool slipped and scratched the surface of the doubler. Not deep, but a scratch that I have since smoothed out almost entirely with just a little scotchbrite pad rubbing.
That said, I still see a very faint straight line (the remants of the scratch) underneath the scuffing left by the scotchbrite pad--although my finger can't feel it when I run it over where the scratch was. I've decided to get it out the rest of the way--should I just continue to use the scotchbrite hand pad (and press a little harder) or is there another abrasive, maybe one step coarser, that I could use first.
I've probably fretted about it more than I should have (this is my first "mistake," except for drilling out two skin/rib holes in my VS at #30 rather than #40), but I know that stress can concentrate on/in scratches, so I don't want to be left wondering about how my HS spar doubler is doing while at 10K feet! Better to have it over-prepped before priming rather than under-prepped!
Thanks,
Steve
