Preparation is everything with Aircraft Painting. Some common Paint strippers are a complete NO NO with Aluminium and it's alloys and Alclad. There are recognised and approved surface treatment chemicals like Alumiprep. The overlaps are your main worry, where the corrosion maybe hidden and inaccessible. Bonding would alleviate that, and make it much stronger at the same time. THICK paint chips easier and adds weight. Acrylic Lacquer can be blended in and is great for repairs or touch ups..
