Front Spar Primer Prep

Had a little time before headed to work so inspected, scuffed and cleaned the front spar and doubler with mineral spirits and isopropyl alcohol in preparation for priming. I'll prime them when I return and can start riveting things together Monday. I'm running low on alcohol and there's none to be found in stores. Don't think Amazon carries it now either. A minor inconvenience when so many are suffering real hardship but I'll need to find an alternative metal cleaning method before priming if I can't get more in the days ahead.
