Corrosion

I live in beautiful southern Wisconsin which blesses us with four seasons that each and every one of us looks forward to year after year. Spring offers new life with budding flowers and new growth. Summer has warm temperatures and outdoor activities, while fall has beautiful colors and crisp air to fill the lungs. Winter is filled with holiday anticipation and fun in the snow. The beginning of each season is anxiously anticipated because we become bored with the previous one. We like the new season but always look forward to the next one, even winter.

CorrosionChanging seasons are desirable for many reason,s but they are also a challenge for the auto glass professional. Not only do we need to pay attention to the procedures we practice but also we must keep an eye on temperature, humidity and the occurrence of corroded metal. Corrosion is a bad thing when it comes to auto glass installation.  It is a condition that must be dealt with, whether we like it or not.

Here are the facts about corrosion as it pertains to auto glass installation:

  • Adhesives do not adhere to rust.
  • Corrosion will always get worse unless it is slowed down.
  • Corrosion is caused by exposure to oxygen.
  • If the “E” coat is breached, the metal will corrode.
  • Typical pinchweld primers are not rust-inhibitive.
  • Corrosion must be dealt with or the installation is unsafe.

I know, more than most, that corrosion is a pain to deal with because up in Wisconsin we use road salt to clean our roads of snow and ice. Salt accelerates the oxidation of metal if the metal is unprotected. So, if a previous installer did not protect the exposed metal on a pinchweld by applying a coating of primer, then the vehicle will be corroded. I deal with this on a weekly and sometimes daily basis. What do we do?  The next series of articles will be dealing with the observation, cause, prevention and treatment of corrosion, as well as how to deal with the customer when corrosion is found and how to get paid for the service you render.
