How a Vietnam-Era Helicopter Fix Became a Multibillion-Dollar Car Care Industry

"Clear bra" started as a military problem. During the Vietnam War, helicopter rotor blades and other exposed transport parts were getting chewed up by flying debris in the field, and the US military asked 3M for something lightweight and inconspicuous to protect them. 3M's engineers landed on a thick, flexible urethane film — soon nicknamed "helicopter tape" — that could shrug off the abuse and simply be replaced instead of forcing a blade repair or swap. It worked well enough that adoption in the field was fast by military standards.

Racing teams noticed next. By the 1980s, US racers were applying helicopter tape to shield paint and sponsor decals from gravel and track debris, and by the 1990s 3M and other manufacturers had refined the material specifically for consumer automotive use — the point where "helicopter tape" became what the industry now calls paint protection film, or PPF.

Modern PPF is built from thermoplastic polyurethane (TPU), and its signature feature is self-healing: heat, whether from direct sun or hot water, lets the film's elastomeric polymer flow back into shape, smoothing out minor swirls and light scratches without polishing or replacement. That property is what separates it from a basic vinyl wrap, and it's the reason PPF has become the default recommendation from detailers like AMMO NYC's Larry Kosilla for anyone trying to keep a car's factory paint intact long-term rather than correcting damage after the fact.

The competitive landscape now runs several major players deep — XPEL, 3M, SunTek, STEK, and LLumar all sell film and certify independent installers — but XPEL has emerged as the industry's most visible name, in part because it's the only one of the group that reports its numbers publicly. In its first quarter of 2026, XPEL posted revenue of $117.4 million, up 13.1% from $103.8 million a year earlier, with net income up 20.5% to $10.3 million ($0.37 per share) and EBITDA up 17.8% to $17.0 million. Gross margin improved to 43.7%. Paint protection film remains the company's largest product line by revenue, but window film adoption grew faster — up 24.8% — and installation labor and dealership/OEM services grew fastest of all, up 24.3%, a sign that the business is shifting as much toward installation services as it is toward the film itself.

That shift tracks with where the broader industry has been heading: PPF stopped being a niche add-on for exotics and track cars once dealerships started offering it as a standard trim-level option, and once self-healing film made the pitch to ordinary daily-driver owners — not just enthusiasts — considerably easier to make.
