First of all, I am too lazy to read above, where is this cab located?
Next,
Don't get frustrated.
1. Is the 3m stripper a product that only reacts with latex paint?
2. Is the black paint latex and or spray paint?
If 1=no and 2=yes,
I suggest you find a product, it is at home depot called Goof Off 2. I just finished a moon patrol rescue with this product and I could not be happier.
I am including a snippet about how I stripped the cab below as well as a link to the thread with pics of the process. I picked all of this up from Oscar's work on a Sinistar cabinet and it worked great.
Good Luck! And if the cab is near Atlanta I might take it off your hands.

Sure, the stuff I used is Goof Off 2 (GO2) . It is the water based, citrus smelling, indoor friendly, version of Goof Off (which is more pungent, etc). The GO2 that I used came in a windex type spray bottle and was not a paste, but a liquid. Same consistency as water. I had to strip the cab indoors hence my choice. Goof Off (1) may work the same way?
I simply laid the cab on its side, the sprayed the GO2 on the entire area to be stripped. Wait between 5 - 15 min (checking periodically to see how fast it is working). When it starts to seperate from the cabinet use a soft to medium nylon bristle brush and wipe the stripped paint away. On the areas that do not lift on the first round, reapply and wait a bit, repeat etc.
Couple of notes:
The key trick here is that the paint used on the cabs from the factory must be oil based wheras the operators generally used latex spray paint for conversions. GO2 is a latex paint stripper so it will not react with the oil based paint underneath the spray paint*.
* This is MOSTLY true, however, I did have a couple of spots that were stubborn so I brushed a bit more vigorously in those areas. When I was finished, I saw that I had stripped some of the factory clear coat or shellac off and in at least one spot thinned that oil based paint underneath. Brush lightly, and accept what you get (IMHO).
Use paper underneath the cabinet or a tarp, the little paint flakes get EVERYWHERE.
Lastly, when finished I used warm water and mild dish soap to clean the sides. I wanted to make sure I did not have residual stripper anywhere continuing to react with the paint and wood.
