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.
