M104 timing cover. What is the preferred sealant for 2011?

[benjay]

Ive read many posts from years back and a few recent. I see that MB has changed its mind on the best sealant over the years.
What is the current recommended sealer for this application?

Mercedes of seattle recommends 003-989-98-20-10 which is REINZOSIL by Victor Reinz.

Is this where the debate ends??? or is there a newer better sealant?

I used the black MB sealant when I replaced the upper timing chain cover seal on our 1991 300CE and have never had any further oil leakage problems.
