4. Paint the rim by brush or spray with a fast-
drying metal primer. Surfaces should be clean
and dry before they are painted. Be sure to
cover bare metal areas on the outside or tire
side of the rim with paint. This is especially
important on drop-center tubeless rims
because warm or moist air is in constant
contact with the metal surface on the tire
side of the rim.
