Hi all. Noticed some very small patches of filiform blisters working under the paint. AC 43-13 suggests bead blasting but I think that may be a bit harsh. A mate suggested a small hand blaster like a HF cheapie and use baking soda as the blasting medium. Would use a mask to limit the area blasted. After blasting, alodine, a primer and touch up with an air brush. Anyone else tried this method of removing filiform corrosion? My top coat is PPG two pack.
