My 70 gal aluminum fuel tank
has come loose. When I installed it 18mos ago, I epoxied it with West System and cloth, but the tabbing on the tank has come loose. The hull
attachments seem ok. I wonder if I did not properly prep the aluminum
. I scuffed it with sandpaper and thought that would make a good bond, but apparently I was mistaken. Now I have a much more difficult repair job because of limited access. I want to do it right this time. What is the best way to get the bond between the epoxy
and the aluminum?
