Title: Stainless steel fasteners on aluminum?
Post by: skippervic on June 08, 2015, 08:27:52 PM

Hi everybody,

I am replacing the forward hatch on 1994 C34. In the instruction that came with the hatch they say I should use stainless still fasteners to fix it to the deck. However, the frame looks aluminum. From what I know using stainless steel on aluminum is usually a bad idea since salt water will promote electrolysis leading to severe corrosion. Does it mean the instruction is wrong or am I missing something?

Coat the stainless screws with Tef-Gel when screwing into aluminum.
