How to Protect Your Car's Paint in All Seasons

Spring: pollen, sap and the first warm sun

Spring brings tree pollen, which is mildly acidic and sticks in the first rain, and the start of the sap season under the mature trees in Tettenhall, Compton and anywhere with a lime tree. Both etch clear coat if they sit through a warm week. The fix is frequency - a wash every fortnight - and a fresh layer of protection after the winter. A wax or sealant applied in spring covers the busiest months for contamination.

Summer: UV, bird lime and heat

UV fades and oxidises paint over years, and it does its worst work on flat panels - roof, bonnet, boot. Bird lime is the summer emergency: it's highly acidic and on a hot panel can etch into clear coat within a day. Wipe it off immediately with a quick detailer, not a dry cloth. Park in the shade where you can. And be careful washing: rinsing a hot car with hard tap water is how water spots form, which is why we use deionised water and why a shaded morning wash beats a sunny afternoon one.

Autumn: leaves, damp and the last chance

Wet leaves trapped in the scuttle and along window seals hold tannins against the paint and stain it. Clear them out. Autumn is also the last dry-enough window to apply protection before winter - a ceramic coating applied in October sees the car through salt season with the paint sealed underneath. It's our busiest coating month for that reason.

Winter: salt, grit and the wash you skip

Road salt is the single most damaging thing UK paint faces. It sits in a film on every lower panel, works into stone chips and starts corrosion from inside. The instinct is to wash less because it's cold; the right move is to wash more, and to rinse the lower panels and arches especially. A pressure rinse with no contact is better than no wash. A coated car makes winter dramatically easier - the salt film rinses off rather than bonding.

The protection options, honestly compared

• Wax - beautiful warm gloss, six to twelve weeks of protection. Cheap, easy, needs reapplying each season.
• Sealant - synthetic, three to six months. Less depth than wax, more durability. Good for winter.
• Ceramic coating - two to seven years. Hardest, slickest, most chemical-resistant. Needs proper preparation and a proper wash routine afterwards.
• Paint protection film (PPF) - a physical film on the front end that stops stone chips, which nothing else does. Expensive; worth it on the bonnet and bumper of a car you're keeping, often combined with a coating on the rest.

The routine that beats all of them

Twice-yearly decontamination - iron remover and clay - to lift what's bonded before it etches. A fortnightly safe wash: two buckets, pH-neutral shampoo, a mitt, dried properly or rinsed with deionised water. Bird lime and sap removed the day you see them. Stone chips touched in before winter. Protection topped up each spring and autumn, or a coating applied once and maintained. None of it is complicated. All of it is easier with a coating underneath and a maintenance visit doing the fortnightly part.

A one-year calendar

March: full decontamination - iron remover, tar remover, clay - to lift what the winter left, then fresh protection for the sap season. June: check the coating or wax is still beading; top up with a sealant or a coating booster if it's dropped off. Bird lime off the same day, all summer. October: the second decontamination of the year, and the last dry window to apply a ceramic coating before the salt - our busiest month for coatings for that reason. December to February: wash more, not less; rinse the lower panels and arches after every salted road; no contact wash if the panel is frozen. A fortnightly maintenance visit does all of it without you having to remember which month it is.

The West Midlands specifics

This region has its own seasonal pattern. Tettenhall, Compton and the older parts of Sutton and Streetly are tree-lined, so sap starts in April and runs to September. The Black Country - Bilston, Wednesfield, Dudley, West Bromwich - sits under industrial fallout all year, which shows as orange specks on light paint and needs a chemical iron remover, not a harder wash. The M6, M54 and M6 Toll corridors mean brake dust and traffic film on any commuter car. And the water is hard, so a hosepipe rinse left to dry spots badly - which is why we use deionised water and why a shaded morning wash beats a sunny afternoon one. Wherever you are in the region, the answer is the same: protect the paint before the season that attacks it, and wash it properly through the season it does.
