[QUOTE="airshot, post: 519858, member: 1183"] Other mitigating circumstances are involved here, such as salt water or electrical grounding. Have boated in fresh water for over 60 years with zero corrosion on any SS bolts that are true SS. My old Starcraft has numerous SS bolts installed by me over 30 years back, I know the current owner, no sign of any corrosion at all around any of the SS bolts. Boat is kept on a trailer and no battery grounded to the hull. However, I have saw saltwater and electrolosis from electrical eat up materials in just a couple years. The biggest problem is we don't know what the actual material is in the items we buy today, while they say SS, there can be little to no nickle in the metal to make it SS. I always carry a small magnet when shopping for SS or aluminum products...any attraction at all will show the material is not pure. Buyer beware is more true today than ever before ! [/QUOTE]
