I would say a heat gun with appropriate funnel attachment (low and slow) with a flat, non-stick "press" pad would allow for the same results and not involve purchasing what I think we should now call a "playfield iron."

My IMDNLE only has a tiny amount on thin posts in the upper PF... Not sure if I should be concerned?

Quoted from Yelobird:

You absolutely could as I said there is no only one solution here just a guide. I preferred this $20 solution as it provided direct to the area repair. I feared using a heat gun as the heat would distribute much further out and possibly create new issues. Plus I have spent more then $20 on goofier pinball tools....

Yeah, I'm thinking you could apply the heat to the back of the press material (metal similar to your iron) and get the exact effect. I just don't want to buy a playfield iron on principle. I'm sure someone around me will though.

I received a replacement playfield from Stern, so I decided to fix my bubbling playfield. I didn't bother ordering an iron as I found a ghetto way of creating my own. I used a cheesy little measuring cup as my metal and heated it with a heat gun. I heated it up to the point that I could barely not touch it with a bare finger. That was the minimum temp that would flatten the clear.

Here is the cheesy tool (filled with paper towel so I could push down on it):

Here is a before and after:

After:

I did about 6-8 different bubbles with this method. The only negative effects are that the circle of the "iron" left a smoother circle that can only be seen in the most perfect lighting, and this will go away in time, and that the bubble sometimes leaves behind a small line where it was unbound from the PF.

Notice the circular line around the far hole:

None of this is noticable with plastic washers down. I put on washers with an inner rim to allow for flex, which will lessen pressure to the PF:

If the iron just hearts up forever, my ghetto heat gun / measuring cup idea is probably better because the heat is so controlled.
