Thanks for all the good wishes, everyone!
I started spreading Everglass over the welded areas today. Got sidetracked by the phone and lunch with Kathy and my niece or I'd have more done ...at least that's my excuse. The doors are all gapped and adjusted so that a small amount of filler along the edges should make them look nice and even. I drilled a couple of locating holes in each hinge so I can insert pins and not have to spend a bunch of time with adjustments when reassembling everything.
Hope to get the major areas worked smooth over the next few weeks. It's a tough time of year to be priming parts with 2K or other catalyzed products, but sometimes you get an unexpected warm day or two. Will have to make the most of what Mother Nature gives me, I reckon.
