Location: Hayward, Calif | Hey Chuck, Where did you get this stuff ?? And what is it called ? The zinc sounds good. When I was working for Mack Trucks, the factory was putting a zinc coating, can't remember for sure but seemed like they put it on some of the frame rails to help prevent oxydation. It was kind of a yellowish/greenish color and the paint went over it. Could you use a primer/filler ? I used it on this 59, and is easy to sand and sculpture. I did use an epoxy on the steering wheel. Takes about 24 hrs to cure and is a little harder to sand than body filler. Jerry |

Location: Perth Australia | I used a zinc weld through primer for a while, but stopped
It made the welds terrible and then primer wouldnt stick to it either

Location: WHEELING,WV.>>>HOME OF WWVA | thanks guys , i have some leftover spray can , epoxy resin plasti-kote , never used . the other day i found some light pitting and further , a couple pin holes along reds drip rail on the
drivers side . after wire wheeling the area i figured i need to have a look to the inside . well theres a sheet metal strip inside that runs the length of the roof line with about 3/4"
or so gap . the only thing to do was spray that gap and left it run to where it is needed . pretty much no other choices for the inside and the headliner was a bitch to separate
from the roof . the rest will be easy after wire wheeling the drip rail . 59 pretty much answered what i was wanting to know but if there are others that have used this , please don't
be bashful with a response . as to where to find any quantity other than a spray can i think the best way is to do a common search , it'll turn up a few --------------------------------------later
PS , this seems to be the best read and i think i would give it a try as fast as anything .

Location: Ontario, Canada | Chuck, I've never used "epoxy" cold galvanizing but I have used "cold galvanizing compound" both by the quart and spray can forever! Amazing stuff!! However, it is NOT a "primer". I doubt that any worthwhile top coating would stick to it. But here is what it will do.
I manufactured hot dipped galvanized boat trailers for many years. We frequently had to do minor alterations to various brackets that had been previously dipped. We would simply grind, drill, re machine and weld small areas on these brackets. One coat of a spray can of the above would protect these areas for years and years. NEVER had a warranty claim for rust in these areas!
I used the fluid compound for all my car restorative work. For example, all "pinch seams". Bottoms of doors and trunk lips and, of course, hollow structures like rocker panels. Sandblast the inner surfaces the best you can and then pour liquid cold galvanizing compound in, sort of slosh it around and pour out the excess. Let it dry for a few days and spray in an asphalt based undercoater. No reported failures in more than 35 years!!
20 some odd years ago I needed a 16' flagpole that had to be strong for various other reasons. I used a length of 2" pipe and welded the required brackets to it. I sandblasted it all and coated it with spray can cold galvanizing compound. Today that pole and brackets show no rust at all!!

Location: Ontario, Canada | There is a possibility that Jerry was referring to a zinc chromate primer. By all reports it was excellent stuff but was very toxic!! Please take extraordinary care when using this!!
