Heat has usually worked for me , Thanks Brion .

Wondering if anyone has used caustic soda (Lye n water) to remove those aluminum corrosion bubbles under paint ?

I wonder if applied with a brush and tape of the area? Hmmmm

Hi,
Caustic soda is one of the things I mentioned that is very effective at dissolving aluminum corrosion, but equally effective at dissolving aluminum. Industrially, it is actually used to produce aluminum oxide. That 1" bolt might need to be cut/drilled out.
Fair leads,
