No it's not a drink made with tomato juice, it's what i have in my sailing box. Has anyone solved the problem? I've had a look for stainless P3, but my efforts have met with limited success.

Wasn't cheap and I had to have it sent from overseas.

How long does it take for an ordinary driver to go too rusty?
Is the cost of replacing them less economical than spending more money on a stainless version?

Are those your backups? If so, You can put them in a ziplock bag and will stay pristine forever

Eliminate the screw driver...Use stainless 6mm hex bolts instead (Bunnings) and use a socket driver. You can put more torque on which is useful for fins with a flange but also very useful getting them out if you leave your fins in the board and the bolts seize to the barrel nuts. The sockets seem to be made of better material that doesn't corrode..I've been using one 10mm 1/4" drive socket with a 10cm extension to clear the footstraps for 4+ years and no sign of corrosion.

Understandable if you want to go sailing with it, but I can't say I've ever had one rust to a concerning level. Usually I find I need a new one because tip has worn to the point where the screwdriver slips. As nice as it is, I don't think stainless will help with that problem.

It is proportionate to your gullibility, fear of sharks and size of your wallet though

loved my one of these, but painful to lose. Went back to the variety that rusts

^ is it too small for a 6mm stainless bolt?

Throw the rusty parts in a jar of clear/white vinegar for a day or two. Wipe clean. Spray with WD40 or paint.
