Can you paint any helmet?
Most Helmets yes - Motorcycle, Karting, Car, Open Face, Motocross, BMX, MTB, Ski all have been painted and the principal is the same.
However the better condition the Helmet, the better the finish. (We paint helmets, we DO NOT repair helmets). A few stone chips and minor surface scratches are fine, we understand that happens and can take those out no problem. We don't fix miracles and badly damaged helmets that have been down the road.
Best finish is on a plain Colour Helmet, i.e. black or white. However we can still paint over factory or previous designs.
