reguarding the corrosion on spools i recently had an internal corrosion problem in my corudo baitcaster. the reel was sent back to shimano and repaired for free(excellent after sales service) . the reel was returned with a letter stating a product called Ballistol should be used on it periodically. so i have bought some and this shit is amazing. the service technitions at shimano use it heaps and said normal water dispersing sprays are to course for bearings. this stuff is a thin oil in an aerosol and can be used on wood, leather, fibreglass doesnt effect mono line. just google to find out more it is worth chasing up . mo tackle sell it. i have used inox lantec this stuff goes gummy and sticky, i wouldnt use it on my reels. ballistol is what i spray under my braid on spools and inside reels as well. it lubricates so well i recently sprayed it on my ram mount for lowrance sounder and even with the ram screw tightened right up the sounder keeps falling over cause of the ballistol on rams ball joints . gotta use it to believe how good it is. shano
