Hot dip galvanizing is the best coating you can have from a corrosion perspective. You can paint it, but it takes some special chemical treating to get it to adhere well, but I don't see any reason, personally, to paint them.
I've used several spray on galvanizing paints and none come anywhere near as good as HDG.
For free, it's a no-brainer IMO.

according to my painter if you wipe HDG down with vinegar it has some type of galvanic reaction which allows paint to stick, never tried it myself

or let it age about six months. The spray I mentioned was for touch up only. The HDG place near me does anything that will fit, we had 12 foot field gates fabbed up and then HDG, will last a long time.

The acid will react with the zinc and you'll get hydrogen gas and zinc sulphate. Since the vinegar is a fairly mild acid, the reaction will be relatively small. I have no way of telling whether any paint will have better adhesion to the sulphated surface or not.

I know the body panels on my pickup truck were galvanized prior to painting, but I don't know the details on the process. FWIW, the paint on that truck is very good after nearly 15 years (well aware that's not the case with all of them from that brand). Point being, galvanized and paint can be made to work.

I did look this up... body panels that are factory galvanized are usually electrogalvanized, not hot dipped.

Sorry? I'm not sure I understand this post Mike. I realize corrosion really isn't an issue where you are, but galvanizing on Rovers has been around since Series days. We just started selling galvanized Discovery 2 chassis as well. I was going to have my front and rear bumpers galvanized but couldn't find anyone within 4 hours to do it.

The only advantage powder coating has over HDG is looks, and that's 100% a personal choice. In every other way it comes far short of the protection of HDG.

Default To galvanize or not

Taint so. Many moons ago, in 1966 for my first Rover, a 1963 Land Rover series IIa, I grew darn tired of the paint peeling/scrapping off my wheels, rusting the steel underneath, so I took them to a radiator repair shop, had them throw the wheels (after I had the tires taken off, of course) in their tanks that strip down radiators for soldering in new cores, to strip my wheels of all paint and clean them up. I later picked them up, and delivered them, along with custom front/rear bumpers I made for same vehicle, to a big industrial shop, for hot tank galvanizing. Never had another problem with the wheels/bumpers rusting, and I never painted over the galvanizing either.
