Final stages of the windows..

Here's the final stages.  The screens have been shaped with files and leave about 20 thou. all round for the clear PVC that will be vacuum formed over them.  There's the mess on the bench to prove it.

Then some more Milliput is pressed underneath them and they are pressed well down onto some greased styrene sheet to make it perfectly flat.

The blobs on the body front are to make patterns for the mud flaps some versions carried.

Here they are, turned over, removed from the car (also buttered) and will be final shaped and packed with Milliput underneath to make a formable shape.

Just a clean up and a scrape across a flat piece of wet'n'dry to finish off.

And that, in a nutshell, is how Milliput window patterns are made.
