Folks,
I have a 1991 110 TUM that I am restoring. The original escape hatch was leaking badly, so I found a complete new one for a modest sum.
I have removed the original - with some difficulty as the screws were severely rusted in. Now I have it all out, I find the original external trim piece was fixed to roof with some sort of black sealant/mastic. This sealant was not the rubbery sort of stuff that is used to seal domestic window frames in walls - it had set fairly solid, and needed to be scraped off (which was easy).
Anyone know what this black sealant is? Its not shown on my parts lists (either the miliary or civvy one).
Failing that - anyone have advice on the kind of stuff to use to reseal the outer trim to the roof?
thanks
Richard
