I resealed the rear main on my '94 YJ yesterday and per the official shop manual the edges of the rear bearing cap should be sealed with a small (3mm) bead of Loctite 515. Unfortunately no one in town, including my local Jeep dealer had any idea what that stuff was. Everyone who knew what I was referring to recommended using hi-temp RTV instead, which is what I used. Anyone know what this 515 is?
It is generically known as anaerobic sealer. It is transparent red, and has the consistency of jelly. It is quite good at sealing minor imperfections between machined surfaces. GM specifies it on a number of applications.
I don't know where you can purchase it, aside from a dealership. I buy mine from my dealership's parts department.

Oh OH OH! Do I know. :)
Also remember that 515 needs several hours (8 higly recomended) to cure before any pressure/vac is applied.
wouldn't it cure in the packaging then? weird....

You would think so, but actually it won't. The package is designed to let air in. The product cures when exposed to metal surfaces and in the absence of oxygen. loctite's website has some technical stuff.
