When someone forgot to use the metal eraser shield as a heat sink when using an electric eraser and "glossed" the mylar tooth on the film, we used a product by Dietzgen that I think was called "Liquid Paper" to rebuild the "tooth" on the film. Came in a big brown bottle and had a brush built into the bottle cap. Worked like a charm!!
Not on Mylar, but always on Linen.......

In the late 80's the Mass. Land Court insisted on linen. I was learning DCA Autocad but no one seemed to know how to plot (with a pen plotter) on linen and I never could draft. POUNCE helped a lot, but the red ink for traverse lines still were very weak. So I copied all the red lines from 0,0 to 0,0 so they plotted twice. That worked!
I'll bet all that Pounce wasn't very good for the plotter.
what's the difference between pounce and Skum-X?
Only the manufacturer.
> what's the difference between pounce and Skum-X?
I had thought that pounce was ground pumice. The other is Bentonite dust. Come to think of it, ground pumice is probably fairly dangerous stuff to have blowing around. Maybe pounce is Bentonite as well. Edit: Yes, the Alvin Company says it's ground Bentonite.
We used to call it a "dust bag." Maybe because of the eraser dust?
Used lots of "Pounce" as well. Worked great for linens and mylar.

You young kids don't know nuttin.
Pounce was a very fine powder which was used to prepare the surface of linen cloth and mylar to accept ink.
Scum-X bags contained ground up gum rubber and were used to cleanup a pencil drawing, generally on vellum. Triangles, templates, drafting machines and parallel rulers would smear the pencil led and the ground rubber would keep the drawing clean. Made a mess on the floor if you had carpet.
I still have both on the desk behind me.
We called the bag a scum bag, pounce was just pounce! What I want to know is, what in the heck was in liquid eradicator? That stuff had to be bad for you.
As I recall there were different eradicators depending the material you were working on. The eradicator for "paper sepia's" bleached the light sensitive coating on the paper. The eradicator for the mylar sepia's softened the coating on the mylar.
Hopefully one had made a "Reverse" print so that you eradicated on the back of the sheet and could draw on the front.
Pounce is that vile substance that was used on coated drawing surfaces like linen and mylar so ink would penetrate the surface and embed into the material rather than just ride on top and be rubbed away during reading and usage.
It was easy enough to use and could be a nightmare to clean away if any was caught in the breeze of a fan and scattered across the office.
Something like a vacuum bag exploding.
After using it a time or two I found the Post Dust-It dry cleaning pad and it was by far easier to use. Still have mine.
It and the powder was one will last a lifetime.

We used lighter fluid. Kinda freaky to squirt a liquid on your freshly inked drawing, but it worked well.

Actually, that is how I remembered Skum-X, but it's still made and sold and when I checked the manufacturer's list of ingredients, they cited Bentonite. When did they change the recipe? I don't know.

When I worked for the City of Sheridan in 1954-1955 & 1957-1959, we used high octane airplane gas to clean linen. When the bottle got almost empty, it was a trip to the airport for a refill. We used to draw the plat, diagrams, etc. on the linen with a 4h pencil, ink over it (freehand) and then use the airplane gas to do the cleanup. Never used Pounce on any drawing, matter of fact, never heard of it until 1969 or the early 1970's.
