Now that I have found it is so easy to post videos I thought I would post another. :)

This is a subject that comes up often, urethane setting front and back glass. This is not for the weak knees, setting a window in urethane has a VERY steep learning curve.

The videos you will see are of a glass man beading out the urethane ready for a window. You will notice by the videos and the photo below that the urethane is not a "rope" looking bead. It is a pyramid shape, this is so as the glass is set down on it, the bead gets fatter and fatter on the glass as it is pressed onto it. What this does is eliminate any air pockets as you would likely get if it was just a fat bead.

So, the tip on the urethane tube has a V cut into it with a razor blade to allow for this bead.

The guy is using a battery powered gun, very slick. Sorry for the big photo, I forgot my work camera is set on larger photos. And also sorry for the poor quality video, I wasn't ready for the guy, he is so damn fast!

Great video Brian. It's been about 15 years since I did my own glass at the shop. I have a glass guy come in and do it.

By the way, someone pointed out to me something I should have mentioned but frankly was embarrassed about. This window is being set on a newly painted pinchweld. That is a BIG NO-NO. You are NEVER to set a urethane window on a repaint, the OEM paint, or EPOXY primer over bare metal is IT, PERIOD. We were doing the epoxy primer thing, it just hit me that apparently things have got a little lax around here. I will be talking to the shop manager about it monday.

There is NO EXCUSE for not doing it properly over epoxy primer (that is on the bare metal) or OEM paint.

Good glass guys are like good bodymen, they are few and far between. There are only about 2 guys in town I let touch my stuff...

Im a lil slower than the average bear but - why? I believe you, of course, but wondering what it is about repaint thats not sufficient for urathane but oem or primer is ok. Just curious what the reason is.

The paint we use in the repair industry does not "grab" like the factory paint, due to the fact that the factory paint is baked on in the neighborhood of a couple hundred degrees.
