Good reason to add a weep hole if the frost didn't make one for you alreadyMy seats fare how you'd expect, not had to replace ever.
BUT- this winter my foot bar must have still had water in it cause it appears to have froze & split the aluminum when it expanded. Only problem I've ever had in 10+ years of storing frames outside.
The ubolts are stainless but they provide zinc washers and nylocks which will rust. It would have probably cost them $0.30 extra per lowpro to supply stainless all aroundI think the ubolts and nuts may corrode if you leave it outside. +1 for hanging from the ceiling. These, http://www.sears.com/shc/s/p_10153_12605_SPM681872201P?PDP_REDIRECT=false&ci_src=184425893&ci_sku=SPM7704196010&sid=IDx20130125xMPTLSx025, work perfect for hanging the frame. I use 4 of them: On one end I hook the front crossbar. the other two are slightly further away than my back crossbar and I use straps to hold the frame in place. I put a lynch pin on my footbar so I can pull it and rotate the frame to flat.
I have two hooks per oar too and have all my oars hanging from the ceiling as well.
Oops, sorry. Should have looked at where you're located. My frames stay outside all summer with no problem. I take them apart & store in the garage in the winter.To clarify, "storage" is not retiring it for the entire winter as we get most of our water then. I just need it out of the way but ready to go when needed.
