Painting the car top cargo carrier as a do-it-yourself project requires some skill with spray painting equipment. There are a number of paint suppliers, some of which are listed below, who provide suitable prime and finished coatings for this use. It is recommended they be contacted for the specific procedures to follow with use of their products.

It is not recommended to remove the top for single side opening boxes. The unit should be properly masked and remain assembled during the paint application. To provide the best surface for paint adhesion, the surface must be prepared prior to applying the prime coat by scuffing it with a light sanding using a 500 or 600 grit cloth or paper and thoroughly cleaned.
