BTW, I've had 3 cars painted over the last 10 years of cheap and very expensive variety and your powdercoated parts will likely get overspray on them in the process. Perhaps spend the efforts to press out old bushings, hit parts with flat black spray can and replace with urethane for now. After paint job, the urethane bushings are easy to remove and have the steel suspension components powdercoated and re assemble. More work but less dissatisfaction. Remeber to mask off machined mating surfaces and close tolerance bushing slip on surfaces as powdercoating can add .01-.02" of thickness.
