Thanks Rick!

i have a customer that builds rolling chassis for 5-6-7 chevies with vette suspensions. i blast all the aluminum stuff with 100-200 grit glass and were going to try the rpm for the blasted stuff to see how it hold up. its nice and smooth once its blasted and he just wants to keep it from oxidizing as they want to leave them unpainted.
perfect test for it i would think.

RPM wax definitely blackens phosphated fasteners and small parts and makes them look much better than phosphated alone or phosphated and coated with grease or oil. Most hair driers should be capable of heating small parts enough to reach the melting point of about 120 degrees. For large parts you may need an oven.

You will want to make the hair drier operate hands free by propping it up somehow and holding the parts in front of it with pliers or similar. I swiped a wire stand from one of my flashlights, drilled two holes in the front end of the hair drier, and clamped the stand to my work table. A smaller 1" brush is better for small parts instead of the supplied 2-3" brush. Keeping the RPM container near the heated zone softens the wax and allows a heated brush to be coated. Like paint, you can brush off excess wax on the rim of the container.
