Replacing bunk supports and galv. corrosion Q`s.

[gofastsandman]

Well class I am starting on my winter to do list and my oh my it has been growing. Should`ve posted this sooner.

I am replacing the bunk supports as they are badly corroded.

Picked up some new alluminum supports,SS hardware,carpet, and monel staples. Got a guy to torch it all in the AM.
I am slowly getting smarter.

The cross members are corroded a little. The guy I bought my Bimini from had a float on trailer from the 70`s.The original owner brushed all the hardware with something grey, and all hardware is galvanized and looks new. Wasn`t a galvanizing product, but the name of the product escapes me. Anyone? He`s moved of course and I didn`t write it down.
Would Tuf Gel last in this application?
POR 15?
All thoughts and suggestions are, as always, much apppreciated.
Cheers,
GFS
