Charlotte Pollen and Your Car's Paint

Pine pollen grains are large, waxy and slightly acidic. When they get wet from dew or rain, they release compounds that can etch a soft clear coat if the panel then heats in the sun. Oak catkins and tree sap add a sticky organic layer on top.

The result is a film that ordinary soap struggles with, because it is bound to the surface rather than resting on it. This is why cars look yellow again an hour after a wash in April.

Wiping dry pollen off with a towel is the fastest way to swirl a car. Pollen grains plus tree grit act as an abrasive slurry under the towel, and the damage shows up as fine circular scratches that only paint correction will remove.

The same applies to automatic brush washes: the brush drags the previous car's pollen across your clear coat.

A ceramic coating or a good sealant gives pollen almost nothing to bond to. Coated cars in Charlotte can be brought back to clean with a hose rinse in April, which means far fewer contact washes and therefore far fewer swirls.

That is the real argument for coating in this city: not gloss, but reduced physical contact with the paint during the three months when contact is most damaging.

Pollen clogs cabin air filters quickly here, and a saturated filter in summer humidity becomes a source of musty smell. Replacing it every spring is cheap maintenance — see interior sanitizing.
