I would be careful with 'weld thru primers' aka cold galvanizing compound, which contain zinc. When trying to weld an already galvanized surface, you will be breathing the burning zinc compound, which is bad for your lungs. I learned the hard way when I first started welding about 15 years ago. You will cough for days. I also found that the welds made thru the compound tended to be inferior in quality, since you are introducing an additional metal into the mix. I would recommend spraying the galvanizing compound into the sealed section after welding is completed, possibly by drilling a small hole. Alternatively, you could pour some POR-15 or Bill Hirsh Miracle Paint into the hole.
