[QUOTE="PSG-1, post: 237811, member: 6937"] It's dependent on a lot of factors. But especially so in saltwater, or if the water is alkaline or acidic. Dirt and other contaminants definitely help accelerate the process of corrosion. Aluminum is the third most reactive metal, excelled only by zinc at #2 and then magnesium as the most reactive. And just because it's a painted aluminum surface, won't guarantee it being corrosion-proof. As I said, I've welded on more than one painted boat that suffered from crevice corrosion from sitting on carpeted bunks, or from having leaves or dirt in the bilge. Things like lead sinkers, or some steel BB's from a shotgun shell sitting in the bilge will make it even worse, as it sets up a battery, with the aluminum being the anode. [/QUOTE]
