Reply to: RE: [VAC] Spec. for orig. window glass, 1962
The original glass is plain 1/8" window glass. In overhauling all the Hehr C1200 windows in the Caravel, I removed the panes, cleaned up the window frames, laid down some black 3/8" wide x 1/8" window mastic tape (from a glass shop in 50' rolls), laid in the glass pane, and then the new Hehr retainer material, siliconed in each corner at the miter.I took pictures of the process, and will be one of the restoration topics (http://www.vintageairstream.com/rr_home.html) once I get caught up with the VAC website.
