Spring is synonymous with blooms, outdoor activities… and the arrival of tree resin , which can drip onto anything under the tree, including your car. In the lesser of two evils, the resin can only be annoying to the eye. In the worst case, it can damage the car paint and lead to rust.
The most neccessary thing to remember is that the longer you wait, the harder it will be to remove the residue. It is best to remove the resin as soon as possible, as it can corrode the paint, especially when the day’s temperatures tend to rise. The heat in fact accelerates the adhesion process of the resin to the paint.
The resin flowing through the tree is made up of nutrients, hormones, water and sugars, and is visible on the surface or bark of a tree when a wound, such as a saw cut, or a natural disease is present. Frosty nights and sunny days above 32 degrees favor the flow of resin after the night, although pine trees exude at any time of the year. This is why resin begins to flow from a broken or cut branch during the spring.
“ Resin can damage a car depending on how it adheres to the vehicle’s surface. The resin droplets of the tree shrink over time, and as they shrink they create stress on the car upholstery due to the strong adhesion to the paint, ”says Dennis Taljan, General Manager Global Automotive OEM Services, Automotive OEM Coatings. ” This tension can end up cracking the finish of a vehicle .”
But tree resin is not the only element of risk; insects can be just as harmful. ” There are cases where insects lay their eggs on cars, ” says Taljan. ” When the sun comes, it burns the eggs and the decaying material can affect some types of finish . “
“as they act similar to tree resin, adhering and stressing the car’s finish ,” he adds.
The finishes of modern cars resist much more than those of 20 years ago. ” The current finishes are designed to withstand a wide range of environmental assaults ranging from acid rain to abrasive dust ,” says Taljan. “Additionally , the clearances formulations have been designed to be more resistant to chemical attack .”
