● Note · Seasonal prep
Detailing before the monsoon lands
Northeast monsoon hits the Strait of Melaka from late October. By September, the air is already changing — warmer rain, denser bug strike, more sap from the angsana trees. We do a particular prep order on customer cars in the eight weeks before the storms; here is the version you can do at home.
Why monsoon prep matters more than spring prep
Tropical rain at 30°C is mineral-rich, hot and persistent — the worst combination for paint. Three things compound it: rubber trim that has dried out over the dry season starts to swell and crack when soaked daily, bird droppings bake faster on a warm-and-wet panel than on a cold-and-wet one, and the headlamp lenses (already weathered from UV) take their final blow from constant heat-soak cycles. None of these are individually fatal; they pile up over six weeks of storms.
Six to eight weeks before the storms — the prep order
Decon and clay
An iron remover and tar remover pass to lift the dry-season build-up, followed by a clay-bar pass. This step is non-negotiable — whatever you seal over now will be sealed in for the storm season. Do it dirty and you bake the dirt under your coating.
Single-stage polish
Even if you do not need a full correction, a finishing polish removes the haze the dry season has put on top. It also opens the clear-coat micro-pores so the next step bonds properly.
Re-coat or re-seal
If you have a ceramic coat in year two or three, this is when we lay a maintenance top coat. If you only have a six-month sealant, this is when it gets re-applied.
Rubber trim feed
Door seals, window rubbers, sunroof gasket. A water-based rubber conditioner restores flexibility before the gaskets get hammered by hourly rain.
Wiper blade swap
The cheapest thing on the list, the most often forgotten. Wipers that drag streaks across the windscreen in light rain will catch grit and gouge the glass in heavy rain.
Underbody rinse
Salt and road grime under the chassis is what kicks off corrosion. A high-pressure rinse from underneath; no chemistry needed.
Headlamp UV seal
If the lenses are already hazing, this is the cut-off — restore them now or commit to replacing them in eighteen months. After the monsoon, the haze is much harder to lift.
What to do during the season
Wash more often, not less. Counter-intuitive but true — a car driven daily in monsoon rain is collecting mineral-rich water on the paint every day. Bi-weekly snow foam washes between September and February keep the topcoat clean. Skip the chain wash; their tunnels are working harder this time of year and are dirtier than usual.
After the storms — the spring reset
March is when we run our highest volume of single-stage corrections. The cumulative damage of a wet season is best dealt with in one careful afternoon rather than a string of partial fixes. If your car came out of October looking flat, do not try to wax it back. Bring it in; we will lift it properly.
Eight weeks of breathing room beats six weeks of mopping up.
Drop the car in before the rain lands properly. Same prep, a tenth of the regret.
