Just bought a gun sails board bag from windsurfing sales and on first impression .. bloody impressed! Will see how it handles the rest of the summer and hope that will have no troubles with the zippers

And the zippers, you wont have any troubles. Have a sail bag and mast bag, not a problem with them. Tough as buggery

Bloody tough alright, I can't move 2 of mine on my gun sail bag no matter what I try

wd40??? Always worked for me

Con****ious say:

"Corrosion is poor man's Loc-tite"

I spray my zippers with silicon on a regular basis. Keeps them purring along.
