Which VHB tape to join polycarb and .040 aluminum?

[signcrafters london]

We built and installed this sign probably 10 years ago, and we need to change the graphics on the face for the third time. The retainer is .040 and it will get a new sheet of polycarb because of yellowing.

Just wondering which VHB tape to use. Double-sided tape (but not VHB) was used the first two times. But I didn't do those installs myself those times and can't remember which tape was used.

Thanks.

I like 3m 468MP for doing that.

468 works well, we also use 45RP or 4950 if you need really aggressive bonding.

i have always used 4950, never a problem.
