There was an interesting program about making London taxis on Channel 4 on Saturday night.
The main taxi body is made up from various bits of aluminium which are glued together. The glue has to be baked to make in harden. It was possible to wait a few days after the glue was applied before it had tom be baked.
There was another part of the vehicle where glue was used, but in that case the glue cured much more quickly.
I did wonder if the glues could be purchased for domestic use?
