There are many different types of resins: High viscosity, low viscosity, thick, thin, expensive and cheap, clear or yellow to name a handful. What makes a “good” resin and how does it affect your repair, your business and your reputation for quality?

Firstly, the aim of a chip repair is to strengthen the windscreen so that no further damage will occur – either a chip becoming a crack through normal driving – or the weak point causing shattering if the car is in a collision.

Ultimately you are looking for a strong repair with good clarity so that visibility is good for the driver and that the car’s value is maintained.

A repair that leaves your garage looking perfect might not stay that way if the resin isn’t of high quality. If the cure isn’t deep enough, the repair doesn’t have the strength required and can crack during routine driving or in a car wash. But once the surface is cured the problem can’t be fixed and a new screen is needed. Or the repair can turn cloudy after a few weeks as the resin reacts to the air or chemicals present on the screen – also leaving the customer frustrated with your repair and with no option but to replace the screen.

One of the best measures of quality is looking for international standards such as the British Standard BS251 and the Australia New Zealand Long Crack standard, both of which are held by Esprit repair products. This standard tests both the equipment and resin when used together and is a good starting point for quality of the repairs.
