My 1996 Trek aluminum MTB has some cancer where I've dripped sweat and missed it
when cleaning & waxing my bike
No broken paint to expose raw AL to sweat, but the salts went through the paint
over time. How long, have no clue
The other spots with chipped/scratched/etc paint are not corroded like the spots
where sweat has done it's work. ALWAYS garaged, except for the times out camping
My cast AL patio furniture has one chair that is always corroding. Even after
sand blasting and repainting with white Rustolium. It's sisters and brothers (other
chairs and table) are just fine sitting out in an uncovered portion of the patio
They are about 25 years old now
On one of my apartments...one units AL sliding doors rot out often
and has to do with the steel railing nearby. Al is sacrificial to FE
The other units have same/similar setups & location to steel railing,
but that one unit rots regularly
My partners in one of my old boats learned to NOT install anything AL without
a sacrificial magnesium slug screwed onto it
Any of you guys with these boats ever have corrosion problems on your outboards?
Depends what chemical make up of the water you boat in, how you hose it off and
how it is stored, IMO
