I think I've found a great aluminum siding adhesive!

Oh OK,
I will have two layers of 1/8" ply on the exterior, which will cover the the spars and insulation.
Don't get me wrong... I wasn't thinking about just gluing the metal skin down on the roof. I'm thinking of the glue just as a way to prevent "oil-canning".

You started me to thinking about the outer skin and I decided to go ahead and install it. I put 1/4" luan on length wise. It went on easily. I'm going to try the adhesive on the skin in the next week or so... I'll let you know how it turns out. See details on my build site below.

Tony,
It looks like things are going without a hitch.
Did you do a test piece and set it in the sun?
BTW- Does that carpet adhesive say that it reamains flexible after it cures?
Just curious because I tore out some carpeting recently and the adhesive was pretty hard. (Don't have a clue what brand it was)

Nope, it doesn't say if it remains pliable... but I went out and checked it again and it has the consistency and sticky properties similar to that of of chewing gum, maybe a little harder but definitely can easily be shaped. I applied the stuff to the sides just over a week ago and it is still very flexible... the tub did say it was water resistant within a week of applying and mentioned shelf life but that was about all.

The teardrop sat in the sun (80F) all day yesterday while I was applying the 1/4" luan to the ceiling. The stuff never changed consistency.

I just bought a gallon at HD. Directions mentioned that it bonded to roughed aluminum boat decks. So, I figured it'd bond to my aluminum. I was going to etch the aluminum with muriatic acid but decided just to sand it to rough it up. Probably be able to glue up the other side tomorrow -- Maybe

Don't know if you can see the yellow pine pollen. It's all over everything My pink insulation has turned green!

I remember a buddy of mine demonstrating oil-canning on the aluminum skin of a Shelby Cobra, when the six foot six, two eighty five pound owner walked up...

In Texas that's grounds for a lynching isn't it?
A real Shelby Cobra sells for more than $500,000.

That's what they refer to when they say "Spring is in the air"!!!

Yeah! I love it. Nice enough to get some work done. Just finished the second AL skin. Used the glue that started this thread - Henry 663. Went on very smooth. Can retack up to 70 minutes. Needs to be rolled after 2 hrs. That's just about my speed

Check back in about 20 years and we'll see how shes holding up. Check for oil canning, bubbles. etc. Heck, just as long as it doesn't blow off driving down the road.

Pine pollen doesn't hit us for another couple of weeks, My driveway washes yellow with it, thank god for Flonase. It's on its way however. Doug Hodder

I just finished installing the .060 aluminum ceiling skin. It went on surprisingly easy! I used the Henry 663 adhesive... we'll see how well it holds up.

I have to tell you, I actually prefer the .060 thickness aluminum to the .035 I put on the sides. It just seems so much stronger. I wish I had used it all around.

Anyway, I deviated from the plans again today. Instead of stopping the skin at the hatch opening, I bent the skin 90 degrees and stopped it at the base of the oak spars that will support the hatch hinge. My thinking is that if water seeps under the hinge I'll see it immediately on the galley upper bulkhead. I also think the aluminum will make a better mating surface for the upper hatch gasket.

Tony, you do awesome work I enjoy visiting your site. And Congratualtions on your new beginning. I'm looking at 3 years 2 months and 13 days at this time

Looks like the top is the next thing for me. I have used .040 for both sides and top. I have considered putting the hatch hinge UNDER the aluminum on top and on TOP of the aluminum on the hatch to follow the water flow. Still thinking The only caveat I see is it would be a bear to take the hinge off if ever required.

Oh BTW I'm using the Henry 663 also. It was very easy to work with. When I drilled the holes for my fender screws about a week later the adhesive came out of the holes stretching like a rubber band. Seems to maintain it's elasticity for expansion (at least for a week!)

Did you guys prime the wood or masonite or just use the Henry's 633 right on the raw material ?

I just slapped it on the plywood.

[TonyCooper]

I primed the sides, but didn't prime the top. I have not seen a difference.

I use the Henrys for a lot of stuff, I glue fabric or rug to interior walls/ceiling. Glue the linoleum to the floor. And Aluminum to a raw wood body. I also use it to glue a sheet of PVC to a sheet of 1/4" laun as a backing for my underbellies. I like the stuff.

Happy Trails
