Pledge? Something spray on. Got the urge to start a pattern this weekend.
Quick spray auto wax maybe. It going up against bondo, no Acraglas.

Again, something that seems convenient on the surface, but turns out to be, not so much. I just use Johnson's paste floor wax. Not that hard to apply and it lasts forever. OK, maybe two percent harder than spray.

art supply stores will carry this
mold release spray

Some guys use Hornady"s One Shot case lube. Never tried it, have always used paste wax.

We used Pam back in the day...I prefer Johnsons wax, the old stuff not this gooey they came out with..Apply with a extra soft tooth brush, so you get in the tight spots..

There was/is a lot of spray products that will work but unfortunately Ive been using Johnsonsand clear wax shoe polish for too long to remember them..

Pam and other oils will contaminate epoxy. Only use waxes. Spray furniture wax will work. You can make your own by dissolving paraffin wax in mineral spirits then spraying it on.

Nothing better. Well... According to the Army Marksmanship Unit. My Instructor from Trinidad worked for the AMU building sniper & competition rifles for around 27 years. He swore by it.

They used it by the gallon and not the spray can. Same stuff.

I ain't changing now. Been using floor wax since 1966, with zero failures.

Yes, for goodness sakes, wax is the age-old release agent.

For normal bedding, Johnson's paste wax is the way to go. If you are mixing bondo with the pattern making the wax won't work as well as light synthetic oil, like Birchwood casey. I have found the bondo sticks to steel with wax.

Of course they use that fancy stuff, it's free to them.
Been using one coat of Johnson's for many years. Works every time.

You will save a lot of time by spraying it on; Here is the time/benefit analysis:
Spray on: 7 seconds. (Believe it or not, I actually timed that)
Wipe on wax: 30 seconds.
So, everyone can see how much faster the spray on stuff, is to apply.
Then;
Wait for the solvents in the spray to flash off: 3 Minutes.
Wait for the wax solvent to dry: 10 seconds.
Ok, wait, I was wrong; the spray is 2 min .75 seconds slower.
But it is modern, so must be better. Everyone use what they want, as usual.

I've used Car/Body Metal wax for yrs and had good success with it.
Always applied it with a tooth brush. Let it dry and left it that way.

Every once in a while I would have a difficult time releasing wood from metal. I always assumed I missed a spot.

Then resently I started using regular shoe polish.
Kiwi brand stuff is what I had on hand, sold in the two part round tin with the twist open tab.
I happen to have brown and black,,both work the same,,and both work even better than the car wax.

Applied the same with a tooth brush, let it dry.

Very easy release, never a problem area holding tight.

I've tried a lot of different things and some of the expoxys will sometimes glue itself to the metal right thru the release agent.
One is common chassis grease. Wouldn't have thought it could,,but it did.

Never used any spray release stuff.

The auto wax or the now much prefered by me shoe polish work.
If the time it takes to apply & dry is too much and you have nothing else to do in those long minutes, then you certainly are in the wrong hobby or trade.

For mold release making fiberglass parts I use this.

I appreciate the response. Ended up giving the top metal and protective duct tape two coats of Minwax paste today. Worked great. I'm sold on it now. Thank you all for chiming in.

Grasshopper,
Wax on, Wax off!!

Picking nits here, but there ain't no such thing as "two coats of wax" or "wax buildup". Wax is an evaporative finish. It "hardens" when the solvents in it flash off in the open air. Two minutes or twenty years, the solvents in the next coat soften and mix with the previous one.
