The best stuff for this is the red variant. I don’t have the P/N handy (it lives in the toolbox in the plane). It is for higher temps, and has the crucial advantage that the whole tube doesn’t go solid a few weeks after it has been opened (a hugely irritating problem with nearly all silicone sealants). I think the 736 posted by Antonio above is the right one. Achim is long gone from here and AFAICT GA generally (bought a TBM).
