I haven't had much success with adhesive only bonds, but want to avoid any hardware attachments.
I am bonding 5" gemini flat cut acrylic letters to aluminum. Is there a good adhesive, more to the point a VHB tape that's works really well?

I buy Gemini letters with their tape on the back. It covers almost the entire back of the letter in strips. They charge 5% more. Well worth it to me.I probably don't need to but I peel off a small area of the tape and apply Lexel in a couple small spots. You will never be able to get them off.

David, you might want to check with this website.... www.thistothat.com also.
They give a lot of information on gluing dissimilar things together. Might save you some aggravation.

I did ask Gemini and they didn't sound real confident on how secure it would be.
Good site, Dale.

It can make a big difference whether the letters are going outside in the weather or inside.
I don't trust adhesives for an acrylic-to-metal bond outdoors. The time tested method is stud mounting. And even then, a real tight fit is not good. Slightly oversize holes with a soft adhesive, like silicone, will allow the letters to float and move independently of the aluminum.
Inside on a lobby wall, however, may never present a problem. Silicone in addition to adhesive tape is smart.

Done tons...The best adhesive for this is:
E-6000...developed originally as a mortar additive when dealing with bricklaying on potentially shifting surfaces. We bought it in caulk tube sizes but now available in 8oz tubes from most crafts stores. It has all of the adhesion that you will ever need on 99% of the surfaces you attach too. The key is small amounts are better than gobs!...just a thin layer with your finger R
