How Colorado’s Intense Sunlight Damages Your Car’s Paint—And How to Stop It

Colorado is known for its sunshine—we enjoy over 300 sunny days a year. While that’s great for hiking, biking, and road trips, it’s not so great for your car’s paint. The sun in higher elevations is stronger and more damaging, which means your vehicle needs extra protection to keep it looking its best.

At Watermill Auto and Pet Wash, we’re here to help you understand how UV exposure affects your car—and what you can do to prevent it.

Why UV Rays Are Stronger in Colorado

Here in Colorado, our elevation makes a big difference. The higher you go, the thinner the atmosphere—and the less protection you have from ultraviolet (UV) rays. In fact, UV radiation increases about 10–12% for every 3,000 feet of elevation, which means your car is exposed to significantly more solar intensity compared to sea level.

What UV Damage Looks Like

When your car sits in direct sunlight day after day, the UV rays begin to break down the chemical bonds in your car’s clear coat and paint. Here’s what you might notice:

• Faded or dull paint, especially on the hood, roof, and trunk

• Oxidation, giving your car a chalky or cloudy appearance

• Peeling clear coat, especially on older vehicles

• Cracking or spider-webbing on the surface

These effects don’t just hurt your car’s appearance—they reduce resale value and can lead to expensive bodywork down the road.

How to Protect Your Car from UV Damage

Luckily, protecting your paint from Colorado’s intense sun is easy with the right routine. Here’s what we recommend:

1. Wash Your Car Regularly

Dust and grime can speed up UV damage by trapping heat and moisture. A clean surface reflects light better and stays cooler.

2. Use a Quality Wax or Sealant

Our self-serve bays at Watermill Auto and Pet Wash include high-quality wax options that act as a barrier between your paint and the sun. A layer of wax reflects UV rays and locks in the color and shine of your finish.

3. Park in the Shade

When possible, park in a garage or under a tree. Even partial shade helps minimize exposure to direct sunlight.

4. Use a Car Cover or Sunshade

For extended parking, a fitted car cover or windshield sunshade can keep your vehicle significantly cooler and protect both exterior and interior surfaces.

Keep Your Car Looking New—Even Under the Colorado Sun

Colorado drivers have the unique challenge of maintaining their vehicles in a high-UV environment. But with regular washes, proper waxing, and a little extra attention, you can keep your car looking as vibrant as the day you bought it. Watermill Auto and Pet Wash makes it easy, affordable, and convenient to give your car the care it needs—all summer long.
