Protecting nuts and bolts from corrosion - at instal.?

[Atticus]

So I got this hose cart for my yard. It's going to obviously have water running through it occasionally and it will also get rained on. The hardware seems okay. I put it together last night "finger tight". Before I torque everything down I was wondering if I could maybe put something on the threaded bolts and nuts which would inhibit corrosion. I don't know if thread locker will do that I have some removable thread locker though I could coat the exposed threads on the hardware if that would help. The nuts are nylon locking type nuts if that makes a difference.

Here's a link to the hose reel/cart:

Also I am wondering if there's a way to protect the painted finish on the frame prior to using a socket to tighten everything down. I could use blue tape around the hardware but that seems kind of tedious looking at 24 or so bolts.

CorrosionX is amazing stuff...
and we have used WD-40 Specialist Long Term Corrosion Inhibitor with good results.

For the threads on the fasteners,this is always a good idea...http://www.permatex.com/products-2/prod ... ant-detail
CorrosionX for everywhere else.

Let me know what you think of the reel cart. I had one that was a bit top heavy and when it tipped it broke the hose connection. I am needing to replace it.

Lots of play "slop" in the handle to frame connection.
