Talking Sheet Metal Adhesive

We've been in a whirlwind of activity this week and we're about to hang our first sections of 16ga sheet metal skinning in the windows. We're headed to town to pick it up but I can't figure out what adhesive we should be using. Could someone fill me in? I seem to remember reading about it on a few threads but I can't find them for the life of me. Additionally, we're planning on using the same screws that secured the metal around the windows. Any reason this is a major mistake?

The plan is to run 4x10 sheets from the top down under the second rail to give us a nice slab side. This means removing the top rail (this will help patch over the emergency exit). Seems like a rather tall run of metal but we're planning on heating it beforehand and there is a slight bend in our support ribs where the bottom rail of the window goes so we think it will be strong enough. Any additional thoughts?

I used Dynatron 550 Auto Seam Sealer. It was recommended in a previous thread.

Some of the most advanced adhesives on the planet are from a company named "Sika". Don't confuse a sealant with a true metal adhesive but there are products that do both. Some of the newer sheetmetal adhesives even have a higher rating than welding.

But to find the right one for any given application it is best to consult with the manufacturer.

Thanks fellas! That put us on the right path.
We're getting close to hanging.

There really is no benefit in heating the metal unless you prefer working in the heat.

I have used 2 Weld bonding adhesives and they are amazingly strong 3000Psi+, all new cars have glued pieces like the chevy express/savanha that door and hinges are glued and many others.

they come in different working times like 30 min working time, 2 hours clamp time and cure time of 8 hours etc.

Professional body shops use faster working times because they know and usually they do not make mistakes but if you are new to it I recommend to go with like 75 min working time.

I used Norton Speedgrip structural adhesives 06420.

3m have this product too and cost about the same and I have used both and they both are really good quality.

You will need a special 2 piston gun and many tips because the tip is used as the cap to keep it stored.

my 2 cents.

EastCoastCB, superdave, we were hoping that 16ga would take care of that.
pepepito, we looked at the 3m panel bond adhesive but the quantity we need made that option totally out of our ball park. I'd never heard of the other, thank you.

Yes if you need a lot of it, it can become really expensive very quickly, in that case renting a welder can be much cheaper.
