Prep of the parts has been completed except for the Forward Spar Caps. They have some left over residue (I call it snot!) from manufactoring. Neither the file, scotch brite wheel nor sand paper seems to have any effect on smoothing them out.
Time to consult my forum friends for a solution...
UPDATE 7/24..Per mfr:
"That looks like laser-induced slag which is normal. You should be able to remove that with a sanding disk or 3M wheel."
