It's a pre-welding or pre-paint treatment used to strip off oxides on magnesium and alloys. It's a hard requirement for pre-welding prep unless the mating faces are mechanically prepared (read: ground to new metal) immediately prior to welding. Welding is done under a gas blanket to prevent oxidation during the welding process. Note that all oil and other contaminants must be completely removed from the mag alloy prior to the oxide stripping, so the idea of using a dichromic acid bath as a way to de-gas or degrease parts is misinformed. All it does is strip off the oxide layer for better paint adhesion. Note also that the window for painting following oxide stripping is short. Depending on temps and RH, you -might- have an hour or maybe two before you see noticeable surface oxidation taking over your cleaned parts. Means that doing it yourself and then delivering the parts to your powder-coater is not a realistic option.

Ya..I just could not copy the paint-to method for the intake...im NOT steady enough.
Another method might be to use something LIKE a grout for floor tile..but doesnt stick.
Apply down to the intake lettering, then sponge off the surface to expose the lettering, then just slob away at it.

Later remove the material you used that doesnt stick to the intake well..and be done.
But I couldnt think of the right material to do that with...
Another idea, would be use a hard rubber ink roller...but couldnt find one..and didnt wanna drive an hour for it..so I used the sponge brush...which was really really effective for bad closeup sight, and unsteady hands.
