A DIY bike painting may seem like a difficult task, but with the help of the Preval Sprayer and without the need for a spray gun or compressor, it becomes effortless. 


By using the Prevel Sprayer and following these simple steps you can get the desired look you want for your bike.


Tips and Warnings:


Always take proper safety precautions when spraying paint, including hand, eye, and breathing protection, as well as ensuring there is plenty of ventilation and no open flames or other source of possible fume ignition.

Certain bike parts require special tools to assemble or remove. If you don't have all the tools to disassemble your bike, take it to a bike shop to have the parts removed and, later, reassembled.

Avoid painting your frame in direct sunlight or cold temperatures.

For a durable, long-lasting finish, prep and cleanliness are key.

Only spray paint in a dry, well ventilated area, such as an open garage.
