Re: LPS #3 is some tough stuff
It dries with a wax like covering/coating and it could be messy when touched later. For galvanized cables .... did you oil them? In a bucket of oil for a day?
Oil them ? No. I don't have a bucket big enough and truthfully, never thought about it.
I have two double sets of 3/8" lines close to 80' each in length. Depending upon the lake level, about 25% of each line could be in the water at any time. The prevailing thought around here is to replace the lines every 5 years or so. However, the portions of the lines not in the water, look brand new. Those sections that dip in the water do get corroded over time. Some folks around the lake use some sort of flotation to keep lines as dry as possible. Some even use "noodles", but I would think that water could enter and stay inside the foam, not solving the problem at all.
After doing a little on-line searching, I did find VpCI 368D that could extend the life of the lines. However, it is pricy, but available as a roll-on product.
We do touch the lines while swimming and the ducks stand on them, so a "messy" product is not an option.
