Based on the tech specs (I've read them all lol), 3M 550FC should be a pretty great option for sealing & bonding, particularly steel panels. Just found a company in Phoenix that has it on sale for $7.25 / 10oz tube. $7.04 each if you buy a 12-pack case. Their regular price is ~$11.00. Cheapest I could find it on Amazon was > $12.00.
I walked in & picked up ours so I don't know what shipping will be. But this place has a huge warehouse w/ tons of inventory we all might find useful. Obvious they do mostly B2B. Might be other deals to be had especially in volume. Don't let the cheesy website fool you. They're not some kid on Amazon selling chi-com crap from his bedroom.

Also the 3M 500-series polyurethane adhesive sealant product family:
