CARPRO FlyBy30 Glass Sealant — 20mL Nano Windscreen Coating, Hydrophobic Rain Repellent & Abrasion Resistant

FlyBy30 is a concentrated 20mL professional-grade glass coating formulated for cars, boats and even shower doors. Applied with the included applicator and microfiber pads, it creates a thin, hydrophobic layer that encourages water to bead and roll off at driving speeds, reduces sticking contaminants and resists abrasion from wipers and car washes. The kit includes a 20mL bottle, an applicator block and two 4" microfiber suede pads for precise, controlled coverage.

How quickly does FlyBy30 start repelling rain?

FlyBy30 is engineered to begin shedding water once the vehicle reaches highway speeds; many users notice improved bead-and-shedding behavior at roughly 30–40 mph. It forms a high contact angle to encourage droplets to round up and slide off, reducing surface film and light scatter in wet conditions.

• Hydrophobic contact angle ≈ 112° for strong beading
• Low sliding angle ≈ 15° for rapid droplet runoff
• Rain repellency typically visible from 30–40 mph
• Works on moving vehicles and stationary glass when rinsed

How long does a single application last and how much is needed?

A properly applied coating uses roughly 10mL to cover a full windshield, so the 20mL bottle can supply about two full-windshield treatments. Longevity depends on environmental exposure and maintenance; unopened shelf life is about 12–14 months, and once opened expect up to six months under normal storage and use conditions.

• Approximate consumption: 10mL per windshield
• Two full-windshield applications from one 20mL bottle
• Shelf life unopened: 12–14 months; opened: ≤6 months
• Resists abrasion from wipers, car washes, dust and salt

How is FlyBy30 applied and how many coats should I use?

Application is straightforward with the included applicator block and microfiber pads. Clean the glass thoroughly, apply a thin even layer, let it flash briefly if needed and buff off any residue; the product supports immediate consecutive coats for added durability and repellency.

• Kit includes 20mL bottle, applicator block, and two 4" microfiber suede pads
• Recommended coating: 2–3 coats on the windshield, 1 coat on other windows
• Consecutive coats can be applied right away for build-up
• Works on all exterior glass types including boats and shower doors

What protection and performance can I expect on everyday roads?

FlyBy30 provides a protective, low-friction glass finish that reduces the accumulation of dirt, salt and light ice while resisting common friction sources like wiper blades and automatic car washes. It improves water management on the surface, which can decrease visual distortion from small droplets and surface film when driving in wet weather.

• Repels water, dirt, dust, salt, ice and snow
• Resists friction and abrasion from wipers and car washes
• Improves droplet contact and sliding behavior for clearer vision
• Suitable for vehicles, marine glass, and home shower doors

Who is this for? FlyBy30 is aimed at vehicle owners, professional detailers and boating enthusiasts who want a compact, high-performance glass coating to improve wet-weather visibility and reduce cleaning frequency. It’s particularly useful for drivers who regularly experience heavy rain, road spray or salty coastal conditions and for anyone wanting a durable, easy-to-apply hydrophobic layer on exterior glass surfaces.
