Another variable would be, how thick/stiff was the mold. If too thin, it flexes
with the back. If just right, it does not flex and comes off easily. If too
thick, you risk heat buildup and waste money.
I use both real vaseline and Walgreens petroleum jelly with minimal difference.
I use it thin, not "slathered on."
The pinkness fades in 2 minutes as I do it.
You got a good texture? Great. Some of our members get the gauzy grid texture
because they don't smoosh the dipped gauze before applying.
Advantages of plaster: set the mold away, for a day or a year, it won't change.
You have time to sculpt the edge and fix flaws in the surface. Reinforce it and
you can cast concrete, resin, fiberglass, whatever.
Very nice model you have there!
