Windshield Repair Forum

For those techs who use compressed air.
If you have a shop, then you have a place to plug in your compressor, but what do you do at a remote location?

Good day ...
I'm somewhat new to this and had a ?. do i need a 500,000 dollar bond for safelite and .....Do you have any suggestions?

I'm still fairly new to this awesome WR business & learning everyday... especially from you guys. With 98 paid repair invoices & over 150 repairs done, I have not yet had to dry anything out, or so I think:eusa_whis (I always wait until after 10 when the sun has dried the dew off of shields) but am freaking out with the onset of winter with rain, snow & ice because I'm scared to death that one of my repairs will crack out; I'll have to reimburse, which I can't afford to do & my reputation that I've worked so hard to build becomes laughable. You say that even if a tiny drop of water is left in a repair, it will freeze & crack out? This causes me great anxiety! I have the Liquid Resins injector system with which I use a brake vacuum pump (19.99 @ Harbor Freight) for the vacuum cycle. It came with a little rubber dealie to put on the end of the hose which I PLAN on using to suck moisture out whenever I see it, along with moisture evaporator from LR, and a little heat applied to the inside. Will this work? Canned air seems silly & expensive & I cannot carry around a generator with an air compressor.

If you're keen to the air blast method I use, I'd suggest Delta's dryer. As for expense in using air; I fill my vessel at gas stations for free, and the capacity lasts for about 7-10 repairs. No need for a compressor or to keep buying pre-filled cans.

I use the Glas-Weld System It does have a good vacuum although they're all about the same. Your system is very strong on moisture, because it seals the small stonechip and takes the air right out, if you put a magnifying glass to the break you can actually see the air bubbles and water dropplets being sucked in. It is a very powerfull tool and if you assist it by slightly pushing your thumb along small cracks to the center, or adding a little heat you can do wonders. Sometimes I try so hard to do so much and the breaks take forever to fix and other times I let my system alone without doing hardly anything and being patient and the results are amazing
In 90degre weather your windshield gets so hot that if you touch it with your hand it burns, so you cool it a little and you repair. So if you use a little heat in the winter to get moisture out or defrost a little longer it aint gonna burn the windshield. I've learned that sometimes patience is best, and do only what is necessary. Your system can do wonders.

Daris, not all screen repair kits pull a vacuum at all, I also ask where does the moisture go when you use a closed vacuum system for drying out?

Still nobody who uses a closed vacuum system for dry out has told me where the evaporated moisture goes?
I really need to know this.

Seems to me that in a closed vaccum system, the moisture would evacuate into the cylinder - or at the very least bring the moisture to the surface of the glass. Then, you would have to dry out the cyldiner (and the surface of the glass) before mounting again and filling with resin.

This might just sound crazy... but what if you used an actual mini-shop vac to vac out the moisture in the brake? It would have to have a pretty good vac and a pretty good seal around the break. Would it work? Might be a good week-end experiment.

Sneck, thanks now we are getting somewhere people thinking about it. Only problem when you use a sealed vacuum the pipe the pump and the chip are one thing, how does the moisture know where to vacate to. Vacuum cleaner yes it does work, so does compressed air blown over the top, it creates low air pressure within the chip creating a vacuum effect.

Maybe we should invite the makers of the Oreck or Tyson to help develop something?:eusa_thin
