Hi Ken. I was in Jakarta 2 weeks ago and will be again next month. Met a guy who had seen a Cobra around town there (I also read in the Jakarta Post that there are three Enzos!).
Hard to say if that particular sealer would help - others may be more knowledgeable on that - but the hot weather there and especially the humidity may influence the type of gasket?
These guys:

Say that they ship internationally.
Hope to catch up at some time!
Cheers,
