Locktight stuff is ####. Smells like vinigar and is real oily. Probably sticks as well as vinigar too.

What we use at work for sealant only jobs is the Toyota genuine stuff. Its not that expencive from memory. Its black and its really sticky. If you get it on your hands you end up coating everything around you in black sticky ####. Or weve used the VW genuine stuff and i think it was the same stuff.

well i used permatex ultra black on my diff, that leaked after a week, and i treated it properly too, cleaned it and everything.
at work we use loctite black maxx, thats good stuff, still going strong on a customers car after 200000ks

Putting the new sump back on this week - gotta buy some gasket goop for the sump - what do people recommend for a CA sump?

Service manual states it should be 3.5mm-4.5mm wide, and to use geniune liquid gasket or equivalent - so keen to hear peoples experience as to the best 'equivalent'.
