Stone chips on Route 9, and why they matter more here

Fast roads and bridge approaches throw stone at the front of a car. What a chip actually exposes, and the difference between one you can ignore and one you cannot.

The leading edge of a car bonnet peppered with small stone chips, several down to grey primer and one beginning to show a rust halo.

Route 9 and the approaches to the Arrigoni Bridge give a lot of Middletown cars sustained speed with traffic close in front. That combination is what puts stone chips into a bonnet.

Most people file chips under cosmetic. In Connecticut they are not.

What a chip actually is

Paint is a stack: primer, colour, clear coat. A stone hitting at speed punches straight through all three, and the bottom of the hole is bare metal.

That metal is now exposed to the atmosphere permanently, with a direct route to it. In a dry climate that is a slow problem. In a state that puts brine on the road for four months of the year it is a fast one, because salt water is a conductor and it now has an unprotected surface to work on.

Corrosion starting at a chip does not stay at the chip. It creeps sideways underneath the surrounding paint, which is why an untouched chip on an older car develops a rusty halo and eventually lifts the paint around it.

Which ones matter

Look at the colour at the bottom of the chip.

Grey or white is primer. The clear coat and the colour are gone but the metal is still covered. This is a cosmetic problem and it can wait.

Black, brown or metallic is bare metal or rust. This one is live, and it is worth sealing before winter rather than after.

The other test is location. Chips on a horizontal panel collect and hold water. Chips on a vertical panel shed it. A chip on the bonnet is more urgent than the same chip on a door.

What detailing does and does not do

Let us be clear about the boundary. No amount of polishing fills a chip. Correction removes material to level a surface, and a chip is missing material — the two are opposites. Anyone offering to polish out your chips is selling you something else.

What a detail genuinely does is get the area properly clean and decontaminated so that whatever you seal it with actually adheres, and put a sealant across the panel so the surrounding paint is protected. That is our exterior detail at $145 and full detail at $275.

Filling the chip itself is touch-up paint, which is a fiddly job you can do at home for a few dollars, and honestly most people should. Clean it, dab it, do not smear it, and accept that it will be visible from a foot away. Visible and protected beats invisible and rusting.

The order that matters

Clean, then seal, then winter. Doing it in that order in October means the chips you have are covered before the salt starts. Doing it in March means the salt has already had the winter to work.

If chips have already gone rusty and are lifting paint around them, that is a body shop rather than us, and we will say so.
