I'm posting to see if anyone's used the Testor's "clear parts cement & window maker" to make windows? I'm fooling around with it today and have before in the past, noteable examples being the windows on my Yard tractor, and Athearn KW Semi.
I have used it for some small windows in HO scale Autos and trucks. It works quite well in the small areas. I think it would not work so well for larger windows.
One thing I've noticed, so far, is to make the intial window, I fill the spot, and tip it upside down, so the glue runs to the outside of the model. About 6 hours later I tip it over and put another layer on.
