Yes, our custom helmet stickers are coated with a protective laminate to make them resistant to wind, rain, water, sunlight and scratching.
However, it may not be possible to apply a sticker across a curved surface cleanly. The stickers will still be durable and stay applied, but a larger sticker may have creases after being applied. For best results, we recommend smaller stickers such as 25 mm x 25 mm or 51 mm x 51 mm. on curved surfaces.
