What's this sticky tape called?
 

The sort that looks a bit like decorators masking tape, but used in
engineering to establish what clearances lie between mating surfaces by
looking at indentations when parts are assembled?

I know just what you mean, but sorry I cannot think of the name..

Replica tape.

I had in mind the material which compresses, so that measuring its
thickness once the two surfaces are disassembled = you know what the
clearance is between the faces.

Isn't that plastiguage ?

But it looks nothing like decorators masking tape

Lead wire was an older method I have seen used to check the bearing
clearance on a ships triple expansion engine. The engineer , the engine and
probably the reel of the wire all dated from before the plastic age.

Never heard of that (although I spent years measuring rough surfaces,
including taking replicas).

Our replica material of choice was Acrulite, this is just methyl
methacrylate monomer which you mix with powdered polymer. It sets in a
couple of minutes.

You can also get replicas using RTV silicone, either two pack putty as
used by dentists for replication, or creamy liquids dispensed from a
double tube syringe through a mixing nozzle.

Metallurgists have a clever technique for large, immovable plant. They
grind and polish the surface finishing with micron diamond paste, then
etch, then apply a drop of acetone and press a thin piece of acetate
sheet on to the surface, and allow it to dry. Done well, the resulting
replica, examined in a metallurgical microscope, gives almost as good an
image as could be obtained from the original metal.
