PRAY.BIKE - DIY SPRAY PAINT FOR BIKES

No drips, No dribbles, No fuss!

The acrylic color coating we've developed is unlike traditional metal or car paint and is suitable for steel, aluminium and carbon parts.

Spray.Bike paint is a dry matte powder coating that doesn't drip, dribble or misbehave in any way and gives a deep thick layer with just a single coat.

Spray.Bike's super easy to use, and perfect for repairing, restoring and refreshing a bike.
