Olive oil removes greasepaint. Read the instructions. I don't suggest you coat an appliance with anything other than ProsAide.
Expensive? What did you pay for the appliance?
Did you price RMG? They are $8.50 an ounce.
Greasepaint in small tubs maybe - $4. If you find close out or Halloween "Makeup Kits" that have 3 colors in a pack even cheaper than that. I bought 3 "Zombie" packs that had an olive green, a grey and a weird yellowy cream color in them for a buck each, years ago - almost 10 years ago. I've done 200 zombies that have used those 9 pots of greasepaint.
ProsAide no tack and regular - $15 bucks each. Will paint 25 makeups.
Spirit gum remover - $4. Will literally last until it evaporates.
Here's that cheap makeup in use - also that's me as the main Zombie - 4 days, 20 hours a day, 100 degrees and the appliance is in a bag ready to go again.

Here's a literal $10.00 Makeup:

$2 Karo Syrup
$1 food coloring
Contacts and dentures saved from another job as well as the powder and oil and such IN MY MAKEUP KIT I'VE BUILT OVER THE YEARS.
I have some greasepaint that is 20 years old. Used it this week in fact. You build up a stocked kit as you go along. The attitude that "this is getting to be quite expensive, and complex" is ridiculous.
Look up the $350 Bigfoot thread I did. It shows the prep of an appliance for makeup that is still in use.
It's not expensive if you are clever. It's not complex, it's how the materials work!
You're gonna gripe about the price of olive oil? Fine -- then use, corn oil, lotion, soap and water - whatever.
Laffo.
