EZ-300 Delta Windshield Repair Kit Review

This is the Delta Kit EZ-300 Series windshield crack repair kit. We will illustrate the spec differences between these two kits and show in the facts and let you decide where you should invest your money. Aside from what we have already shows in the Delta Kits vs Ultra Bond overview, the biggest take-away you need to know is that Ultra Bond Kits Are Easy To Use and made for the technician. Out of shier frustration from some 30 years ago Richard Campfield, inventor and founder, developed tools that made repairing chips and cracks fast and easy. Aside from the ease of the tools, Ultra Bond also focused on safety standards and we follow the FMVSS (Federal Motor Vehicle Safety Standards) and built the United States Windshield Repair Guidelines to ensure our products maintained our customer's pre-factory windshield strength. Let's take a look at how these two kits match up.

The first main difference here with this windshield chip repair kit is that it only repair chips! Ultra Bond's professional windshield repair kit can also handle long cracks and has an additional wonder bar crack-opener. In fact our Crack Master Bridge Structure is agile and can easily handle long cracks, even long cracks up to 18 inches long !


Ultra Bond Tool design does not need additional tools to do cracks, simple just put in the correct resin in and go. Ultra Bond shines in its mechanical ability, strength and versatility! See the differentiation specs below:


  • Waste Resin
  • Resin Refill After Every Repair
  • Mandatory Break Down and Take Apart After Every Repair
  • Manual Probe Flexing
  • No Flex Bridge Structure
  • Recommends 18-20 CPS Watery Thin Windshield Repair Resins
  • Can cause an underfill because of Injector Distance from Stiff Cup and no cure under pressure.
  • Little Control, Suction Cup is Used to Level and Stabilize


If you are new to the windshield repair industry, what you don't realize about this kit is that you are buying or investing into a kit that repairs chips only with water thin resin that can make you less efficient during your windshield chip repairs. Delta Kits is company of great salespeople, and their business model was designed to keep overwhelming resupply orders going.

Windshield Chip Repair Kit

$995.00

The Ultra Bond Standard Chip and Crack Repair Kit gives you much more than the EZ-300 windshield chip repair kit. The powerful crack master bridge can be split apart into a long crack slider tool and a crack-opener. The second crack-opener comes in handy with longer cracks. It can also be reconfigured into a star-leg flexor for chip repairs. These are the three main tools and they will enable you to repair both chips and long cracks which doubles your earning potential.  At the price point of $995 you are getting a lot of leverage when you are in the field. For instance, you can make more money because you can fix long cracks in a windshield. You can charge up to $150 for a crack repair versus just $60 for a chip repair. When you factor in your cost of goods sold and marketing, it makes sense to be able to repair cracks and chips in one kit. Lets review the specs on this kit below:


  • Lowest Cost Per Repair
  • Injector Chamber Holds More Resin
  • No Mandatory Break Down Needed
  • Star Flexor I Enables You To Set On the Legs Ensure an Overfill.
  • Crack Master Bridge Design Creates No Tension on The Windshield
  • Crack Master Bridge Gives You Compression Needed to Inject Thick Resin
  • Uses Structural Adhesive Resins, Our Tool Enables You to Inject up 100-200 CPS in chips.
  • Overfill Created Because of The Design


Best thing about our kit is it is very simple to use, all you need to do is practice. Ultra Bond developed a plethora of windshield repair training materials, manuals, and videos. If you are limited with your current kit consider purchasing a Crack Master Kit or Upgrade Crack Repair Kit and get on with making repairs without committing to another kit.

Starting a New Business? Here's What You Need To Know?!

windshield-crack-repair-kits

If you are starting a new windshield repair business or adding professional windshield repair to your current business, you need to make money on every opportunity you come across.  With the Ultra Bond Crackmaster Kit you have two injectors and seven tool options that will enable you to repair all simple and complicated chips (Stone-breaks) and all long cracks without re-figuring tools.

 

If you repair just chips you will no doubt run into long cracks every day. If you don't repair them you just lost $100 +.

 

Did you know that over 90% of consumers will choose a long crack repair over a replacement? Not only because it costs hundreds less but only takes less than 30 minutes. A repair is also far safer than a replacement. A repair does not alter or compromise the many safety systems that are connected to the windshield. Safety Systems connected to the windshield include: the airbag crash pulse, roof crush, occupant retention, airbag backboard, impact and penetration protection from road debris, occupant ejection and the newer vehicles with ADAS (Advanced Driver Assist Systems) must be re-calibrated if the windshield is replaced which costs more money and more time for the consumer. Often the consumer after a replacement must then go to the car dealer for re-calibration of the ADAS.

 

The Crackmaster Bridge Structure splits apart into two long crack repair tools - a long crack slider and a crack opener. With the Standard kit you have two-crack openers instead of one with the Starter Kit. Two crack openers make the long crack repair easier and faster than one crack opener.

 

Three Wonder Bars give you all Seven Tool Configurations so no matter what job or obstacle you come across on a repair of a chip or long crack you will have the tool you need to effectually do the repair.

 

Ultra Bond professional windshield crack repair kit is the only windshield repair system that has been proven in lab tests, real-world performance and in court to be stronger than a new windshield.
