I know this has been answered before, but I want to see if there are updates or fresh ideas to this problem.
Because it is taking so long to do these wings. a lot of my pieces of alum. still have the blue covering on it. I am finding out that with time, this stuff gets really hard to get off first of all. Secondly, along the edges of some pieces, I am starting to see very small amounts of corrosion (small funnels, maybe only a quarter to half an inch long develop. These pieces are stored in a nice dry temp. controlled basement, so I thought I would be immune to this sort of thing.
Should I get rid of all the blue wrap left on all the pieces or can I still leave it on so it doesn't get scratched up during the build?
Also, what's the best way to get rid of this type of corrosion? Is scrotchbrite scuffing enough, along with priming, or do I need to chemically treat the area before priming?
