EZ-350 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 shown in the Delta Kits vs Ultra Bond overview, the biggest take-away you need to know is that Ultra Bond Kits Are Fun and Easy To Use and made for the technician. Over 30 years ago Richard Campfield, inventor and founder, developed tools that made repairing chips and cracks fast, easy and effective. Aside from the ease of the tools, Ultra Bond also focused on safety standards and we follow the ROLAGS FMVSS (Federal Motor Vehicle Safety Standards) and built the United States Windshield Repair Guidelines to ensure our products maintained your customer's factory windshield strength. Let's take a look at how these two kits match up.

EZ-350D Pro Chip Kit Review

ez-350d-mobile-pro-windshield-repair-kit

$1050.00

This EZ-350D Pro Delta Kit windshield chip repair kit for chips only is virtually no different than the EZ-300S Delta Kit other than the fact they have two bridge structures, which as stated previously and below are designed for repairing chips with water thin resins. Maybe you can do more than one car at once, but realize that you are injecting water thin resins which are not as strong as thicker resins. Their spring injector offers little vacuum. At a $1,050  price point the EZ-350D Pro Delta Windshield Chip Repair Kit, you are just getting an extra tool. 


  • Wastes Resin
  • Resin Refill After Every Repair
  • Mandatory Break Down and Take Apart After Every Repair
  • Manual Probe Flexing With Your Thumb, Can be Painful To Do
  • No Flex Bridge Structure
  • Uses 18 CPS Watery Thin Windshield Repair Resin
  • Can cause an underfill because of Stiff Cup and no curing 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 it won't help you repair more chips or make you more efficient during your windshield chip repairs. Delta Kits is a company of great salesmen and their business model is to keep overwhelming resupply orders going.

Standard Crack & Chip Kit

Ultra Bond windshield chip and crack repair kit

$1095.00

The Ultra Bond  Standard Chip and Crack Repair Kit gives so you much more than the EZ-350S Pro Windshield Chip Repair Kit.  We offer you the windshield repair tech every tool needed and the mechanical ability to handle both windshield chip repairs and long crack repairs. At the price point of $1095 our Standard Chip and Crack Repair Kit beats the EZ-350S in overall performance without spending more money. Now if you want to do multiple repairs at once, you can always buy an extra Crack Master Bridge Structure or an Wonderbar Crack Opener or even a Wonderbar Star Flexor for dealing with Star-Breaks and those legs without using a probe. Having an extra crack-opener just helps you in the long crack repair market for handling cracks up to 18 inches long. Our long crack-openers are long and necessary for opening up the windshield to create the needed overfill. This brings up another valid point, with our kit you can earn more than double with the money you invest! You can charge up to $150 for a crack versus just $65 for a chip. 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. Let's review the specs on this kit below:


  • Lowest Cost Per Repair
  • Injector Chamber Holds More Resin
  • No Mandatory Break Down Needed
  • Convert Wonderbar Crack Opener To Star Flexor, Avoid Using Probe
  • Star Flexor I Enables You to Set on the Legs Ensure an Overfill.
  • Crack Master Bridge Design converts into a Long Crack Slider Tool and a Crack-Opener
  • 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.


Best thing about our kit is it is fun and 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 frustrated with your Delta 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.
