Is there a chemical or "easy" method to remove acrylic (1/4" thick) graphics from Dibond that are mounted with 3M VH 4941. Some parts of the logo are 6"w x 18"h with alot of VHB on the back.
Making a new sign is an option, if the labor for removal is going to take more than 1-2 hours.
I tried heat,"fishing line" and Rapid remover...no success.

There is ALOT of VHB on this thing. "Sawing" thru w/fishing line took 5 minutes to go thru 1-2" of tape, not to mention the loss of all feeling in my finger tips.

Hiya Thom, IMHO, a new sign would be in order. You can try piano wire or a guitar string to "saw" through the tape. However, it may be time consuming too. Anohter thought would be combination of heat, squeegies (to wedge the letters up) and Rapid Remover may work quicker.

I've used a plastic strap off a box before; worked pretty good but it did take some Rapid Remover and picking to get it all off.

I would make a new sign if I was only trying to save a piece of Dibond, but here's a method that I got from others on this board, and it worked like a charm.
Get a Japanese saw. It's a very flat, flexible blade saw that can easily get behind the acrylic. It cuts on the backstroke and only takes a stroke or two to remove a letter. I removed six by six inch aluminum panels off a sheetrock wall in no time and didn't damage the wall at all.

Never heard of a "japanese saw"...but will look into that. The wedge and rapid tac method is showing some progress.
If the substrate was the only consideration I wouldn't hesitate on the new sign. But this has a 2" deep brushed aluminum edge along with mounting mounting frame.

I may soundsimple,....but "twist it off". Those tapes are impossible to pull straight off. Grab hold of piece and twist in either direction,..or both. It's always worked for me. Let us know please.

Twisting does work on smaller or narrower letters, it's the large graphics that are giving me the trouble. 6" x 18" pcs. (some as large as 8" x 23" w/ VHB every 2".
I was hoping for ACME brand instant VHB disolver..."as seen on TV" or youtube...
At least I now know how well this stuff holds!

If you can lay the panel flat, I would pool up some Rapid Remover and let it soak, That is one of the keys, let it soak. Then I would use a couple of plastic putty scrapers they cut them right off.
Remove what is left and your good to go.
What you did not tell us is how many on what size panel.
That would determine whether to save or replace.
