Also I found a way to make the glass have a more modern look. I plan on making all the chrome trim satin black but wanted the windows to be dark on the edges like new cars so the trim doesn't look so stark. I tried and failed to make the black glass primer stick (came of with the tape on the edges) then I remembered something from art class, Etching cream. It gives the glass just enough texture to make the black primer stick better. I did a step by step for any who are interested. I will just illustrate the back window. I went off a new Camaro for reference.
Start by cleaning the glass.
Tape off the front side of the glass (part that faces out)
Flip window over and start the mask.
I laid out tape starting from the edges to keep the same contours as the glass
You can use various sized round objects to get the radius you want....
I went tighter at the top.
Fine line up against the tape and around the lines you mark
Come inside with wider and wider tape and eventually cover the whole center with tape and paper. I taped over the paper since it would get wet later.
Next: pull off the original tape and you have the center nicely masked.
You need to use a glass cleaner without ammonia in it, and clean it good, make sure you get the residue the blue fine line tape left behind. Good lighting helps.
Etching Creme or paste. I got this at a craft supply store, there are probably other brands out there..
Brush on and let set per directions. I brushed it in one direction and went back around and brushed opposite direction. Try not to brush into or under the tape. The radius edges will want to come up, so make sure they are all pressed down good!
Wipe off with water and wet rag and clean again with glass cleaner really well.
