Sonax BSD is a goated product. The water beading is crazy with this even though my car is already ceramic coated.
Pros: crazy water beading

I have had the o ring seal leak very slightly on the J35 v6’s a couple of times… so on occasions I have put a very very thin coating of Honda bond on the o ring itself and then assembled. The gasket surfaces absolutely must be clean and dry
Pros: prevents slight leaks
Vehicle:
Honda
I like Blacklight as a sealant.
Pros: I like it
Oh yeah, when you re-seal everything (cam timing covers, etc) use Honda Bond from your local Honda dealer @ $10/tube. I've had much better luck with this on machined surfaces, being leak free on many personal cars for 5+ years.
Pros: leak free for years
Vehicle:
Audi A4
Loctite 518 is good stuff, however there is an "old" and "new" formulation for it. The old one is amazing for sealing cases.
Pros: amazing for sealing cases
Cons: poor gasoline resistance
I've used the loctite 518 to good effect.
Pros: good effect
Ive been using Victor reinz sealant forever on the oil pans.
Pros: long-term use
I have never had any issued with it. I've use for every pan or area required by Audi and VW. One tube from VW goes a long way. About 4 to 5 pans.
Pros: never had any issues, goes a long way
i am putting on a new oil pan since i stripped the drain plug hole in mine. i ordered the replacement from adirondak (germanautoparts.com) and the tube of sealant (Kolbenschmidt brand).
