No biggie! I looked all over, but everyone seems to be going away from a sealant coating. I will look into the Halomar, but I just finished up installing with Permatex #2 on the outer race and splines, and sealing the nut itself with Teflon paste.
I may have overkilled it, but I don’t want to do it over in a few months!!
In my experiance the seals if properly installed rarely leak.I usually install the seal,seat the yoke,then lay a bead of sealer in the groove for the washer filling that area,install washer and pinion nut.It has always worked for me.
I used to use whatever silicone I had laying around in the shop, but I've changed to Permatex 81182 Gear Oil RTV. The aftermarket ring and pinions and yokes we use on the race cars are all over the place for spline fit....this cured the issue of gear oil creeping around the yoke splines.
