Sorry, didn't want to panic you or anything.
I'm not sure how bad it will be, I just think it can't be a good idear having any amount of salt somewhere you don't want it. If it can be avoided.
I tie the new cable to the mouse line then create a nose cone on it with some parcel tape and add a small amount of Silicone grease for extra slippage, which is probably equally as bad for another reason.
I will of course be corrected by somebody with more knowledge of the situation.
