The RPM was kind of like a dried paste. We had to heat it with a split-second blast from our heat gun to get it to a state where we could get it on the brush. Sticking the jar in the sun may have worked too. Once we figured that out, we spent about 30 seconds brushing the RPM onto the arc of the steering arm. We let the part cool down to room temperature and then gently wiped off the excess RPM. The surface did darken a little after application, but at the same time, the sandblast process really brightened up the surface.
