Airduct making tool

[jo90]

Not sure if anyone will recall this but i saw some time ago an ad from an american car site that sold a tool to produce airducts in bodyshells. It was effectively a two part iron press, forced by hand. You heated the shell with something like a paint stripping gun (carefully of course) just enough to make the shell warm, and only just pliable. You could then, using the tool with one part outside and the other in press an airduct into the shell.

If anyone recalls this, and even has a company name or site, it would be appreciated

Cheers
