Last year, an owner in Phoenix sent us a photograph of a 2019 Honda Accord sedan. The car had spent the previous twelve months on the roof level of a parking structure — covered, technically, but the cover was a $38 generic polyester unit f

Most car covers marketed as waterproof block rain from outside — and trap humidity against the paint on the inside. That second part is the one the category does not talk about.

A paint scratch from an ice scraper runs $150 to $800 to touch up. Hood oxidation from one winter of salt and sun exposure — a single-panel respray — costs $400 to $1,200. Full repaint damage from road salt working through compromised clear

Most covers sold for the Subaru WRX are labeled "sport-fit" or "performance-cut." Most are standard sedan patterns with an elastic hem at the bottom. The WRX's fender flares and lower roofline are not reflected in the pattern. We're aware t

Most products marketed as 'all-weather' SUV covers in this category are a single sheet of non-woven polypropylene. Factory cost: $3 to $7. The entire marketing argument is the word 'all-weather' on the label — not a tested mechanism, not a

An SUV roofline is flatter than a sedan roofline. That is not an advantage for UV exposure — it is a disadvantage. We finished UV cover testing on sedan profiles in Buena Park and assumed the same recommendations applied to SUVs. They did n
