Spring: pollen is acidic enough to matter
Tennessee spring pollen isn't just unsightly. It's slightly acidic, and when it gets wet — by morning dew, by rain, by a humid afternoon — it bonds to the clearcoat and starts to etch. By the time pollen looks "crusty," you're already looking at a paint job that needs more than a rinse.
What to do: rinse the car every few days during peak pollen weeks. No contact, no chemistry, just water pressure. A maintenance detail every 3–4 weeks throughout March, April, and early May keeps you ahead of it.
Summer: UV degrades protection and tar bonds fast
Middle Tennessee summers run hot, humid, and bright. UV exposure breaks down sealants faster than people expect — the same product that lasts 6 months in Seattle might give you 3 in a Brentwood driveway. Construction zone tar bonds to lower panels and rocker panels and gets harder to remove the longer it sits.
What to do: refresh sealant or top a ceramic coating with a maintenance spray every 4–6 weeks. Spot-treat tar promptly — a dedicated tar remover, gently, on a cool panel.
Fall: sap is the silent paint-killer
Fall in Brentwood and Franklin means tree-lined streets at peak beauty. It also means sap drips, especially under maples and oaks. Sap is acidic and resin-heavy, and it etches paint fast — particularly if the panel sits in the sun and gets hot. By the time you notice it, the clearcoat underneath is sometimes already marked.
What to do: don't park under heavy-canopy trees for extended periods if you can help it. If you do, rinse and inspect daily. Sap that's been on the paint less than a day usually comes off with a clay treatment in a full detail. Sap that's been baking for a week sometimes requires polishing.

Tennessee uses brine pretreatment ahead of winter storms — a chloride solution sprayed on the roads to prevent ice. Brine is sticky, clings under the car, and works its way into seams, suspension components, and bolt heads. Visible salt residue is bad. Brine that you can't see is worse.
What to do: rinse the underbody after any brine event, even if the car looks clean. A dedicated undercarriage rinse is part of every maintenance detail we do in the winter months. Wheel wells, suspension arms, and seam edges deserve the extra attention.
A four-season protection schedule
For most of our Brentwood and Franklin clients, the year breaks down like this:
- March–April: maintenance every 3 weeks, full detail post-pollen.
- May–August: maintenance every 4–6 weeks, refresh sealant mid-summer.
- September–October: watch for sap, full detail before leaves drop heavily.
- November: full detail with fresh sealant — your winter protection.
- December–February: maintenance detail after each brine event; underbody rinse focus.
