I'm looking into powdercoating my hubs but I am concerned about the spline/race area. Any tips ideas I can do so I don't get that thick stuff in there? Perhaps the coater will have something but I wanted to pick a few brains here before I do this.

 

the powdercoater will shield the splines from the powder

 

Yea the coater should know

 

I did mine, and all I used was some high temp tape specially made for powdercoating. it's not a problem whatsoever.
