Just some before and after, sort of, info about my bus windows people might find useful -
I tinted some windows and painted the ones that would be covered on the inside, used good quality tint and, since I can't find my before pictures, I'll just say that the ones I painted black and the ones I tinted 5% black looked just the same when I was done. Can't remember the name of the tint and don't have a link to it since it was about 6 years or so ago I did this.
Here's how it looks after 6 years or thereabouts - the window on each end are painted and the three in the middle are tinted.
The tint's faded some and the upper right panel has a crazy pattern in it that showed up a month or so ago.
THe window on the right was spray painted with Ace flat black enamel, the one on the left was rolled with Ace flat black enamel. The one on the left looks just the same as when I painted it.
As for the paint, I didn't have any idea about painting glass, but hey, I'd been in enough city bars with storefront windows painted black not to be discouraged!
I after some research it seemed like an OK idea, so I just followed the instructions for what to do to the windows as if you were tinting them, I scraped the windows with a razor blade, washed 'em with 1/2 and 1/2 vinegar and water, then windex and started painting. Shot the right hand window above and ran out of spray paint and rather than dash to Ace for more, just switched over to regular enamel I had and rolled it on the left window.
When I fix the right window guess I'll just scrape it and roll it, since it seems to hold up OK. Just seems that there's something different in the spray that makes it not as 'stretchy' as the glass, or the other way around.
