quote Jerry Ahrens:
I’ve always used the primer when using the gel seal, or any of the anaerobic sealer. You can actually order that stuff in a kit form, that comes with a smaller tube of the sealer and a small can of primer. I’ve always got that through Mercury Marine, but I’m sure other places have it. The surfaces must be absolutely clean before applying this product…. no grease, oil etc.
I’ll get shot at for this, but I’ve always used the old school 3m 847 for the crankcase halves of these old engines. But I always use the anaerobic stuff on modern motors.

Well, I won’t be the one that shoots you! The 3M 847 works great and is more forgiving that the gel seal when it comes to prep…This is not to say that the surfaces needn’t be properly prepped when using the 3M847, but it is more forgiving. There is nothing worse than starting up a freshly rebuilt engine only to notice an external crankcase leak….
