Just bought a new car? Do these four things first

Dealer prep is not detailing. The lot wash that happens before you take delivery is done fast, usually with one bucket and a mitt that has been across a hundred other cars. A surprising number of new cars already have wash marks in the paint before the owner drives them home. If you just bought something you plan to keep, here is what we would do in the first couple of weeks.

1. Look at it in the right light before you do anything

Pull it into a garage and put a bright light across the paint at a low angle. You are looking for swirls, buffer trails and any panel whose finish does not match the ones next to it. Do this early. If there is damage from transport or from the lot, you want it documented while it is unambiguously not your fault.

2. Decontaminate, even though it is new

New does not mean clean. Cars sit on rail cars and open lots for weeks and pick up industrial fallout and rail dust, which are tiny metal particles that embed in the clear coat and then rust in place. Run your fingertips over the paint through a thin plastic bag. If it feels gritty rather than glassy, it is contaminated. An iron remover and a clay treatment pull that out. Sealing over it locks it in.

3. Correct only what needs correcting

If the light test turned up dealer-installed swirls, a single light polish will clear them. This is also the one time we will actively tell you a car probably needs less than you think. Factory clear coat is thin, and every correction spends some of it. Fix what is visible and leave the rest alone.

4. Protect it while it is still perfect

This is the real argument for coating a new car. You are not repairing damage, you are preventing it, and the paint is in the best condition it will ever be in. A ceramic coating or a quality sealant now means the next several years of bird droppings and road film land on a sacrificial layer instead of your clear coat. Do the interior at the same time. Fabric and leather protection is far easier before the first spill than after it.

One thing to skip

The finance office will offer you a paint and fabric protection package, often for several hundred dollars or more. In most cases it is a low-grade sealant applied by the same people who did the lot wash. Decline it and put the money toward the real thing.
