...are usually some alloy of aluminum. It appears from my own experience, from talking to other boat owners, and people that do bottom painting......
....virtually NOBODY realizes that MOST bottom paints are not compatible with, nor acceptable to be used when painting aluminum.
Bottom painters slather the same paint on the aluminum that was chosen for the fiberglass..... in spite of manufacturers recommendations to the contrary and much documented information concerning dissimilar metals corrosion.
If you have bottom paint on your aluminum pieces, I urge you to check and see what paint was used on your boat....
