It's never been left wet in a boardbag except for driving home after a sail.

Handy. I've seen a lot of boards get damaged from being wet inside board bags. I only use board bags for transport now too

Large amounts of stainless fixings sold as 316 stainless (the higher grade) are still going to corrode. Lots of fixings sold as 316 are not in fact true 316 at all. Some unscrupulous retailers brand 306 as 316. Some imported 316 is garbage. Highest grade is Monel steel not very common but used in large vessel through hull valves etc.
Much of the corrosion, discolouration, and staining on stainless is due to galvanic action. Yachts install multiple anodes to help correct this but stainless still gets staining or worse corrosion. Using products like Teffgell helps but will not totally prevents this.
The sea is a harsh environment, boards get stored wet, whether rinsed or not foot strap neoprene covers hold salt and water, stainless fixings and brass inserts both induce currant flow through the board, carbon is a great conductor, something has to fizz. Just check your fixings every so often, most don't fail unless neglected for a long time, the plastic fails around them due to the expansion.

Sounds like a good excuse to buy a new board.

They don't make them anymore.. The boards all good. I just replaced the tail plate adjuster screw with a new on and it's as good as new.

Where did you get the tail plate screw Sue? I have one of the early metal head ones and I can't turn it without tearing my fingers.

try naval jelly - it dissolves rust. i havent tried on eva, so mebbe try an inconspicuous location 1st as they say,....

We used to use emer gel to remove rust stains on yacht sails. Might be worth a go
