Yes, orange was one colour. The name blackjack comes from the same sort of
product they used pre 1939 and the name just stuck (no pun.)

Sorry, a bit knackered when I wrote the above. To clarify, it was applied
where surfaces were mated with fasteners or over spot welds in areas where
water spray from wheelhouses and chassis deflection points was likely to
find its way in. Never used as a sandwich on spot welds 'cos there would be
no electrical path and the weld wouldn't work.

Sounds like the same sort of thing

The other thing you could use is an epoxy resin putty - there are various
types on the market. Once its mixed, you roll it into shapes like playdough
and kneed it into small crevices, then smooth it over. This stuff cures
fully in about 3 hours or less and it's brilliant. Could be expensive and
sets steel hard. BUT - once it has SET, it HAS set. I've seen it used to
stop leaks from fuel tanks and IMHO its every bit as good as welding. I
suppose we're now getting into sledgehammer and nut country but as a last
resort.............?
