   Sherwin Williams makes a Prep-Rite primer that will work on glass. Once that's on, then you can paint on the primer. Since glass is transparent, that white primer may not be a viable solution though.

   White will work perfectly, as the paint will be opaque. Thanks!

   Kilz makes a pretty good primer for glass - it's nearly impossible to get off.

   Darn, neither Prep-Rite nor Kilz will work for me. According to their websites, glossy surfaces have to be abraded first.

   Does any kind of sandpaper abrade borosilicate glass?

   Look at Prep Rite "anchor bond." Read the data sheet, it says for use on glass. It's in pdf format so I can't give a link or copy the info. You'll have to look it up. Sorry.

   I went back to the Sherwin-Williams website, but this time I browsed the sections for paint professionals instead of DIY. You're right, Don, it was there. The product is PrepRite ProBlock (latex) and it works on glass. Thanks.

   I think you might find anchor guard a bit better then pro block. It is specifically made for hard, high gloss, low tooth (non abrasive) surfaces. I've never used it on glass, but it works great on high polish, porcelin tile.

   Don, I couldn't find a product called anchor guard. Are you sure you can't post a link to a .PDF? Could you copy the address of the file and post that?

   It's a funky site but do this from the Sherwin Williams site:

   1. select products and services

   2. select the search button, upper right corner

   3. select product browser at the left

   4. at the top, select "interior"

   5. at the top, select "primersealer"

   6. 4th selection--select "bonding primer"

   This is "anchor bond" sorry, not anchor guard---Hit label info for a picture of the label, under general info hit the data sheet for a list of what it works on.

   Good luck, it's not a very intuitive site.

   What happened with the chemicals....no etching seems odd...

   Have you considered sandblasting the glass.  You can rent/buy a fairly cheap sandblasting unit that will use just playground-grade sand and a fairly small compressor...and etch that way.

   Etching cream doesn't work on Pyrex, which is chemically different than regular glass. There's an etching product that could be strong enough to etch Pyrex, but it's a little too dangerous for my comfort.

   Years ago I used a sandblasting machine to put a satin finish on metal, but instead of sand, it used little glass beads. Pyrex, perhaps?

   Anyway, I don't necessarily want to etch the glass; it was just one way to ensure that the latex paint will stick.

   Is there any kind of sandpaper that will scratch glass?

   I used to paint glass that was applied to MDF painted side in and held in place with silicone cement.  The painted side was dull and lifeless, but the unpainted side reflected like mirror  I usually used black but other colors would work.

   1. Carbide will scratch glass.

   2. There are etching creams at most crafts stores like Michael's or Crafts 2000 that are used to etch water glasses.  Since the etching is done with fluorine, it should etch any silicone based glass.

   3.  As I said above, I used to paint window glass without etching.  I did it with the cheapest spray latex enamel you could buy.  Care had to be taken in the application (extremely light coats with 3 or 4 usually being sufficient for coverage). The paint had to dry 24 hours between coats and 3 to 4 days after the final coat and the glass had to be scrupulously clean before starting.

   Hope this helps.
