Summer's Hidden Damage

While Ontario drivers focus on winter salt damage, summer quietly causes significant harm: UV radiation fades paint and cracks interior plastics, high interior temperatures (up to 70°C/160°F in direct sun) accelerate material degradation, bird droppings and tree sap etch into clear coat faster in heat, and road tar becomes more aggressive in warm weather.

Exterior Summer Protection

UV Protection for Paint

Fresh wax or sealant application in early summer provides UV-blocking protection. Ceramic coatings offer superior UV protection lasting multiple summers. Park in shade when possible — even 30 minutes in direct summer sun is meaningful UV exposure.

Contaminant Management

Summer contaminants (bird droppings, tree sap, bug splatter) damage paint faster in heat. Remove them within 24 hours when possible. Keep a quick detailer spray and microfiber cloth in your vehicle for immediate spot cleaning.

Tire and Trim Care

UV degrades rubber and black plastic trim. Apply UV-protective dressings to tires and exterior trim monthly during summer. This prevents the gray, faded appearance that makes vehicles look older than they are.

Interior Summer Protection

Dashboard and Trim

UV-protective interior dressing applied in late spring provides protection through summer. Consider a ceramic interior coating for longer-lasting protection.

Windshield Sunshades

A reflective windshield shade significantly reduces interior temperatures and UV exposure on the dashboard and front seats. Inexpensive and highly effective.

Leather Care

Leather dries out faster in summer heat. Conditioning every 2-3 months (vs. every 6 months in winter) maintains suppleness and prevents cracking.

Summer Washing Frequency

Every 2-3 weeks in summer is appropriate. More frequent washing removes UV-damaged contaminants before they cause permanent damage. Less frequent allows contaminants to etch into clear coat.
