Porsche or VW Indy shops will have the anaerobic sealer locally if you can't find any at a regular parts house.

I like sealers that keep the mating surfaces from fretting . Hondabond or Yamabond #3 is available at bike shops in Anytown USA

Loctite 518 gel seal works fine.

2011 and newer Etecs have blue gel seal I Dono why they changed the color after 40 yrs of red. It doesn't seem any different.

These have served me well. Here's a few fallen soldiers from the last couple months.
