It's how corrosion progresses under organic coatings and has has nothing to do with microbial-influenced corrosion.
I''m a licensed, professional metallurgist and corrosion engineer.
Thanks for the information and the link.
Is that how rust gets under chrome plating and causes it to lift?
Having worked with all types of metals and metal processing for well over 50 years I hadn't seen "rust spiders" under paint until I started collecting bikes built in the 1980's. None of my bikes from the 1960's or 70's have this kind of corrosion.
