My wings are complete and ready for priming. The kit is two years old. On removing the blue plastic I have found some corrosion on the skins but only in the area of the manufacturers spec. details. I assumed the ink is water based and corrosion is developing underneath the plastic post manufacture.
I am planning to scotchbrite, and acid etch prime. On a trial area of corrosion after using the fine (grey) scotchbrite the Alclad dulls off to a very dark grey. Nothing will remove this stain, even if I continue scotchbrite I had hoped to remove all of the corrosion prior to priming now I'm not sure if I'm doing more harm than good!!
The question is what is the best technique for dealing with this type of corrosion?
Do the areas of corrosion have to be completely removed prior to priming or does the process of acid etch combat further corrosion development?
Paint and finish solutions greatly received.
