school bus or vertical truck windshields

[cwrepair]

I've been doing windshield repair now for six years and do a lot of repairs on vertical glass.The equipment I use is equipped with stainless piston screw type injectors which get great pressure. My problem though is it takes longer than a typical repair due to the resin wants to leak out a bit from the back of the reservoir when im pulling the air from the break. I use a syringe to apply the resin in the bottom of the injector reservoir but still lose resin and eventually pressure due to being inverted. I end up having to reload once more to complete the repair. I would like to ask for the opinions of the people that do these repairs what is the best methods and more appropriate equipment I could be using for this type of repair on inverted glass? Thanks

A couple suggestions.
When do a repair on vertical glass set your bridge below instead of above the repair. When you do this it will allow you to adjust so that your injector will have a slight cant up instaed of exactly perpendicular to the glass. You don't want much, just enough to keep the resin from flowing out the back of the injector.

Another suggestion is to try an injector with a tip on it that allows you to preload the injector. This can really save you a lot of aggravation on vertical repairs.

Thanks, I do use that method of placing the bridge below the repair and that does help but I think your suggestion on finding some type of preload injector tip would be the best thing for me to do. I just have to figure out which one on the market is best for these repairs. Thanks again

I do have a vertical pit adapter from the old Novus days but I just use the plastic type injectors and just front load them. You will always find these jobs a little harder but it is what makes a good tech stand out from the rest.

Failing that park the vehicle on a hill ( facing up not down ) Just joking.

Yeah, maybe that or I could just run the trucks up on some wheel ramps in the front.....LOL

The LR injector is ideal for vert glass you front load the injector and its light so the it doesnt tend to drop off

[cwrepair]

do you mean liquid resins? I looked at it and it proclaims to perform well but I can't get past the fact that it is made out of plastic. I wished I could find one that is in stainless that would accomplish the same resuts.

don't be afraid of plastic

I have always used plastic injectors without a problem as long as they have a good quality seal, which I am sure goes for any injector.

If you don't have a CDL, moving the trucks to a hill may be a problem. Much easier to let the air out of the sets of tires;)
