[missinginaction]

Is this what we're looking for?

Or do we just want to use polyethylene sheeting like home builders use? Like this one.

I got mine and it works perfectly, by allowing the "amine bloom" in the curing process to move to the outside of the taffeta to be peeled off after the curing process allows bogging/sanding/painting to proceed easily...

If you look at the last photo in the article , or the one I posted in post #5, you can see the film is flattening the end of his finger as he bend s it back, so I do think he is using film .030" thick.

Here is a source for the stuff, and there are others. Google 'polyester sheet', a brand name is 'Mylar'.

Ta daaaa - mystery solved. That 'shirt box' material I bought and used was called, Mylar. I always thought it was some other kind of Plastic, not just a trade name. Its been sold by my local FG shop for years, exactly for that purpose.

Cost wise though, it was a lot dearer than those links you supplied.

The other great use for it is as a sacrfiicial mould. Lay some objects on a table, lay the Mylar on top, and apply FG. The Mylar will stay in the shape you laid it (sometimes with the help of a bit of goo on the underside) and that FG will cure with a perfectly smooth curved and fitting underside.
