when spooling up spectra, some people use electrical tape around the arbor to keep the spectra from slipping. it's fine for fresh water, but not so good by itself for a salt water reel.

yup, plain black electrical tape. who knows how many seasons this has been on.

and this is what you get. funny, this one. lots of corrosion under the tape, absolutely none on the sides of the spool.

this has to be cleaned down to the bare aluminum. and at this point, opinions diverge. what i do is give the spool a light coat of yamaha marine grease, cleaning off the excess. i'm betting that the engineers at yamaha have grease that is acceptably salt water resistant. some guys use car wax. i dunno....

then it's a coat of breathable flex wrap, then take the spectra six turns around the arbor, then a six turn uni knot, then loaded under pressure equal to 50 to 75% of the anticipated drag ranged (but you knew that last part already).

gotta protect those spools!!!!!
