my 4/3 is chafing me around my neck worst than any wetsuit I've ever owned. Someone actually approached me at work and ask if everything was alright at home because they saw the rope burn around my neck haha. It's more than just a little chaf it's actually grinding away my skin and burning. I scrubbed the hell out of the colar and my hyperflex poly fleece, and didn't seem to do the trick. Can't afford a new wetsuit and well I don't got much time left with the 4/3 any how. Any suggestions, does vasoline ruin the wetsuit? I'm open to anything
