Why Resin Quality Matters

In talking to many repair techs, it’s common to hear that there is very little difference between one manufacturer’s resins and another’s. If you accept that logic it would make sense to use the cheapest resin available.

However, when you consider that the resin you leave behind in the repair can make the difference between a happy customer and an unhappy customer, it only makes sense to find and use the best resin available.

That leaves the question, how do you determine which resin is the best?

Here are a few guidelines to help in determining a quality windshield repair resin.

  • Have the resins been tested against the ANSI and/or BSI standards by an independent certified testing laboratory? Did they pass? It is important that the testing be done by a certified independent lab to make sure that there is no bias in their conclusions.
  • These tests should include:
  • Tensile Strength testing which includes evaluation of adhesion and cohesion, how well the resin adheres to the surrounding glass and how cohesive it is itself so that it will not pull apart.
  • Weathering to ensure that the resins will hold up to the elements over time.
  • Stability tests to determine how the resins hold up to color stability like fading or yellowing as time goes by.
  • Does the manufacture offer a variety of resins and do they have the expertise to recommend which resin to use based on viscosity as it relates to the type of damage, temperature, etc?
  • Does the manufacture offer tinted resins? And can they explain when they should be used and which tint should be used for which application?
  • How long have the resins been used in the field, and what are their track records?
  • What is the resin’s chemistry? Does the manufacturer claim that they are acid free? Are they really? (This brings up another subject – acid free resins, we will address this in another blog).


GlasWeld resins are tested and proven to meet and exceed industry standards for quality including ROLAGS, ANSI and BSI.

Can you afford to use the best repair resin? Let’s do the math:

  1. If your injector used 4 drops of resin to repair a break then one ounce of resin will repair 200 breaks (minimum).
  2. Very inexpensive and lower quality resin can be bought for $25.00 or less per ounce. At that price you are spending about 12½ cents for each repair.
  3. Top quality resins are running between $50 and $60 per ounce. That equates to 25 to 30 cents per repair.

So the question is not can I afford to use the best resin but, can I afford not to?

Being the best windshield repair technician in the area means doing what is best for your customer. Giving him the best repair experience means having the best expertise and using the

best equipment and materials available.

Being the best at something is not easy. It’s more than what you do, it’s who you are. It’s a mind set and a life style. Our industry needs leaders; we need technicians that that are the best at what they do.

Are you the best windshield repair technician in your area?
