After a disappointing start last weekend, the second of the window frames picked up, has turned out to be a little treasure. This one has no holes in it anywhere on the outside, and I don't care about the two breaks in the window channel track. They will fill with Butyl sealant

I didn't dare expect anything other than flakes of rust, requiring a bit of welding at best. But I was pleasently surprised.

A thorough beating with the wire cup and a few minutes work removing hard silicone sealer from the window channel, showed this to be best one I have gotten to date. Lathered all the rust with a good quality converter and put it to bed for the night.
All going well tomorrow (bad weather predicted again), I hope to get the radiator air ducting painted, and should get primer on the window frame. I want to do some plastic filler smoothing along the rough edges of inside bottom track, where modest pitting has occured. If I get this done early and weather holds, I
may get the color on window frame too!
If I had known this frame would be a goer, I would have bought the rubber seals while in town today. Still, it'll keep for Monday P.M.
