Three of the posters here are the same guy playing games.he was banned here twice under other names. Do a little research you will find the join fate of the biggest culprit is 3 days after the last ban. I'm not falling for the junk anymore myself.

I too am confused by the video 14U2Ponder posted, that is clearly not a bullseye but does clearly show damage being filled without pulling vacuum first. In fact in this instance pulling vacuum 1st would not do any good because as the video shows the cracks reach the surface so vacuum would simply pull air from the surface.

I am also confused by the last post from GlassStarz. Three of the posters in this thread are the same person and that person has been banned under other names? If you truly believe that please send me a PM and I will investigate. Posting under multiple names pretending you are someone else one sure way to get a permanent ban from this forum.

More importantly, some of you apparently completely misunderstand how a pressure first system works. I have never said I use pressure only to fill a bullseye. What I have said, and continue to say, is that regardless of the system you use both pressure and vacuum are used to inject resin into the damage and remove the air. The ongoing argument is which method is more efficient and on that point some of us are obviously never going to agree. Our videos of bullseye repairs clearly show that the air is being removed, not simply injecting resin under pressure.

And getting back to the topic, air around the edge of a bullseye is not the same thing as a pressure ring, which is actually resin forced out between the glass and the PVB. I'll post a video or two for better understanding as soon as I get a couple of free minutes.

As promised:

Closeup of air being removed from a bullseye using a pressure 1st system. Note that the air is not simply being pushed to the edge but is actually removed from the damage through repeated pressure and vacuum cycles.


This one demonstrates how quick a bullseye can be repaired no "visible" air or pressure ring at the outside of the completed repair. Note that the repair was not cured under pressure.


***These videos were created specifically to show how resin is injected and air is removed using a delta kits windshield repair system. Although the results are undeniably acceptable, I do not advocate rushing through the repair process. For best results please follow the mfg suggested repair procedure for the type of windshield repair system you are using.

UV reaching the surface can vary even on a bright sunny day. These are some reasons why I recommend using a high quality UV lamp.
The amount of UV that the earth’s ozone absorbs varies depending on the time of day, time of the year, the latitude and altitude.
At around noon the UV rays at the highest. At this time, the rays have the least distance to travel through the atmosphere. In morning and afternoon, the rays pass through the atmosphere at an angle and their intensity is greatly reduced. Time of year will also vary the amount of UV because of the angle of the earth. Latitude is also a factor. The further away from the equator the amount of UV decreases also because of the distance and angle. UV intensity increases with altitude because there is less present atmosphere to absorb the UV rays.
Use the UV lamps manufacture recommendations for cure times and you can be sure that the repair is cured properly. No guess work.

Thanks, Can you recommend a good inexpensive lamp that works well. I know you said ask the manufacture recommendations, I'm on a super tight budget till I get up and rolling.

This is our current best seller. It it is both powerful and durable and comes with an extra battery, charger and windshield mount. It is also available without the mount for $49.95 and without batteries and charger for even less but the package deal is the best value. http://www.deltakits.com/shopping/ultra ... nd-charger There are lots of look-a-likes on the Internet, some of which perform well and others that are junk, so when you go shopping just make sure you purchase from a reputable source with a money back guarantee.

There are also considerably less expensive lights, including one we sell, but I don't recommend them for anything but a backup.
