D3 fin block

Hey guys, I'm skiing on an RCX right now and am liking the ski, but I've had it for less than a year and need to replace the fin block for a third time.  Now, I ski on salt water, and the salt definitely causes the screws to corrode together somewhat and then strip or break easier when I'm adjusting the fin.  I tried to be more careful and not tighten the screws down too tight but then my fin moves every so often.  Is this something anyone else has had any experience with?  The only thing I can think of to reduce this is just to take the fin block off the ski every once in awhile and soak it in fresh water.

The fin block is aluminum.  The screws are stainless steel.  The two do not work well together in salt water.  Replace the hardware with siliconized bronze with pipe dope (PTFE paste) as an anti-seize compound and your life will be easier.
