Windshield Repair Forum

During this week, I was doing two vehicles at the same time and did not dry out the one with two small bullseyes. I used the Delta bridge and the bullseyes filled nicely, after about 20 minutes I pulled it off, pit resined, tabbed, fetched my light and after fitting the light noiced that a thin black line had formed where the bullseye edge had been. If this was outside I would have cured under pressure and not noticed it. I strongly suspect a minute amount of moisture being pushed back by the resin pressure, as I have not had that for a long time as I dry ALL my repairs with a minitorch before doing.

Sneck,, I have a question about curing under pressure or on vacuum. My manufacturer says always cure underpressure but I have noticed on several occasions that the damage looks much nicer on my last vacuum cycle before the pressure. Do you feel it would hurt to cure on that vacuum when it looks totally great?

Tooldini, I have never heard of (or even thought of) curing while in a vaccum cycle. Great things are invented by people trying something new. I would get a practice windshield, wet it down and dirty it up to mimick true work in the field.

Make and repair lots and lots of breaks.
Cure 1/3 of the breaks under pressure.
Cure 1/3 of the breaks static (no pressure, no vaccum).
Then cure 1/3 of them under a vaccum and let us all know what you find. I would be very interested in knowing your results.

My gut feeling is that the curing under a vaccum idea may get a laugh by some folks. But so did Coprenicas, Einstien, Michael Faraday and Gene Roddenberry, amoung countless others. Do an experiment and see what happens. You have already mentioned that the repair in question looked better under a vaccum cycle. So the next step is to duplicate it in your evil repair lab.

yeah maybe I will give that a try. I have never really though much about it till I noticed on a vacuum that the damage seemed to have dissappeared. Of course on a practice shield this would be done

thanks

I'm only talking perhaps i in 50 bullseyes does not fill quickly with a few pressure/vac cycles. With the odd one that has a pesky bit of air trapped after several cycles, a bit of heat from the inside on the vac cycle helps. One repair on a very easy looking bullseye once took me nearly an hour, but it came good in the end and had to pre cure (very rarely do i pre cure) - it just came back every time i tried to remove the bridge.

I am using epsrit bridge and resign.

Hey, Since I have been using my moisture evaporator on just about every repair, even on hot days, I dont come across a lot of the problems I had in the beginning. Moisture IS our enemy! So try using a method of evaporating on your repairs and see what happens.

BTW, what is "resign"??? lol. yu mite wont too chec yer spelign. jk

I have always found this forum to be helpful.
Criticising the spelling of other form members is not helpful.

I agree...This is a windshield repair forum, not a spelling bee. I know you put jk (just kidding) at the end, but let's be completely respectful of all members.

Thanks.
