I agree that the big names like 3M will probably have what you need. To get more specific, it might help to understand your application. There are not many places in an RV build where adhesive is the only thing holding two pieces of aluminum together. On my aircraft, there are none.

3M Scotch Weld 2216 has been around over 45 years, still made. It was used in the amazing Sorceress Reno biplane racer back in the '70s.

3M makes lots of structural adhesives these days: https://www.3mcanada.ca/3M/en_CA/p/c...ural/two-part/

Need to know application.
Application? major, safety critical structure or secondary structure? all in sheer or are there pull-off loads?
Environment? Moisture? temperature changes? fuel? vibration?

Default Easy

Ec2216 is the industry standard, but prep is everything. So bonding airplane parts is not like model airplane building, be informed.

Go do a little searching in the Bede aircraft world on the inter webs - they glue a lot of structure together!

Default 3M 5200

3m 5200 is amazingly strong and bonds very well to metals. Scotch bright and clean as prep. Home Depot sells it in a small tube. Get the quick cure. Be aware it is a permanent bond. I used it on my flap and aileron trailing edges. Easier to use then pro-seal but equally messy. Wear gloves.

The tech data I saw mentions several materials this works on, but none are metal. Any idea why? Corrosion? Adhesion? Liability?
