Good morning,
We have been working on the wings of our RV-10 and ready to put the bottom skins on. This weekend, I noticed overspray from the porta-cool on the skin and it appears to be corrosion. Here are two photos:

I tried cleaning with acetone and MEK. Upon doing so, it knocked off the grit and made the surface smooth, but it looks more cloudy.
I checked the pH of the porta-cool water with hot-tub strips. It is greater than 9.0.
Is this, in fact, corrosion? If so, is there a way to clean it and stop the damage? It has only been on for about 2 weeks time. I am a little concerned that we will button it up and not see it. We have been priming the interior surfaces with SEM Self-etching primer.
Any advice is appreciated!
