The Summer Sun and Your Paint

Heat, UV and bug season — keeping gloss through the warm months.

What the sun actually does

Sunlight is the quiet enemy of a finish. Ultraviolet light slowly breaks down the protective layer on paint, and heat accelerates everything else: water spotting, wax failure, the fading of trim.

The damage is cumulative and mostly invisible — until it isn't. Protection applied early is far less costly than correction applied late.

Wash cool, dry fast

In summer heat, wash in the morning or the evening, never on hot paint in direct sun. Water and soap dry on hot panels in seconds, leaving spots and streaks that etch into the surface.

Dry immediately with a clean microfibre or a blower. Air-drying is what causes the mineral spotting that dulls a finish.

Bugs, tar and bird droppings

Summer brings the season's most damaging contaminants. Bug residue and bird droppings are mildly acidic and etch paint quickly in heat — the longer they sit, the deeper they burn in.

Keep a quick-detailing spray and a microfibre in the car, and remove them the day they happen. Front ends and mirrors deserve a look after every highway run.

Shade and shelter

Where a vehicle sleeps matters more than anything applied to it. Covered or garage parking slows everything above — the cheapest protection available.

If the vehicle lives outside, a fresh layer of protection before the season and again at midsummer keeps the finish ahead of the sun.
