Maybe I've just been lucky ... but in over 50 years of fly fishing (the last 20 almost 100 % 2-handers), lots of different reels from very inexpensive to pretty darned pricie .. I've never had a speck of rust.

By def. reels are going to get wet, inside and out. Seems darned silly that a 'quality reel maker' would use "parts" that were subject to rust. Need to lube them, yes, but not as 'rust protection.'
