Hail season and your paint: what a coating does and does not do
A ceramic coating will not stop hail denting a panel, but it does prevent most of the water spotting and etching that a storm leaves behind on everything it did not dent.
A ceramic coating will not stop hail denting a panel, but it does prevent most of the water spotting and etching that a storm leaves behind on everything it did not dent. Those are two separate problems and it is worth being clear about which one you are solving.
What hail season looks like here
Denver sits in what forecasters call Hail Alley, and the metro area sees three to four significant hailstorms in a normal year. The season runs roughly May through August.
That frequency is the part people underestimate. A car parked outside through a Front Range summer is not facing a rare event.
What a coating genuinely helps with
A coating helps with everything the hail did not physically dent, which on most vehicles after most storms is the majority of the paint.
A hailstorm leaves behind more than impacts:
- Water spotting. Hail melt carries minerals, and it dries on hot paint in minutes. Those spots etch into the clear coat if they sit.
- Micro impacts. Small stones and grit driven by storm wind land alongside the ice.
- Surface contamination. Debris blown out of gutters, trees and roofs sticks to a wet panel.
On coated paint, meltwater sheets off rather than sitting in droplets, which is what stops most spotting from forming at all. What does land rinses off instead of bonding.
What it cannot do
It cannot stop a dent. A ceramic coating is roughly the thickness of a sheet of paper split many times over, and hail arrives with enough energy to deform sheet metal. No coating, wax or sealant changes that.
Paint protection film is thicker and does absorb some smaller impacts, but it is a different product at a different price, and it is not a hail solution either. The only real protection from hail is a roof over the car.
What to do after a storm
Rinse the car as soon as it is safe to, and do not wipe it dry while it is still gritty.
The order matters:
- Rinse thoroughly before touching the paint, because storm debris is abrasive
- Wash properly rather than just rinsing, so nothing minerals up as it dries
- Look at the panels in low sun before deciding whether you have dents or spots
- Deal with etching quickly, because it gets harder to remove the longer it sits
If the spots have already etched in, that is a correction job rather than a wash. Paint correction starts at $399 and takes water spot etching out of the clear coat rather than off it.
The sensible order for a Colorado car
If you are going to coat the car, do it before the season rather than after. Our ceramic coating starts at $299 and holds two to three years, which covers three hail seasons.
Coating a car that has just been through a storm means either sealing the spots in or correcting first. Correcting first is right, and it costs more than doing it in April would have.
We come to you anywhere within 25 miles of Broomfield, which after a storm is the difference between getting the car rinsed on Tuesday and getting it rinsed when you have a free Saturday.
