Re: painting rims
One trick for masking the spokes is to use soda straws. Paper or plastic will work but look for the smallest diameter you can find. Slice them them snap them around the spokes, tape the tops so they don't slip away from the rim and spray away. When the paint is dry just pull the straws off.
