I have a steel quonset style building that I would like to seal against the elements. Originally, the sections were caulked between the overlapping ends. Replacing the original seal would not be possible without disassembling the building.
I'm planning on trying to seal the edges of the seams with a good roofing silicone, unless there is a better solution, like a rubber coating over the whole thing? I'm sure there are products out there that I don't even know exist, but some of you smarties can clue me in.

It was 10 years ago, so I don't remember the company, but, it was good stuff. It wouldn't be cheap though.
I'll google and see if I can find the stuff I used.

I've never worked with a product like this, and was wondering if it would set-up enough to apply without it running off, (like a bedliner adheres to the vertical sides of the truck bed), as the roof/wall arcs to near vertical at the bottom?
I'll contact these guys and see what they have to say.

If looks are important, then coating the whole thing would be a necessity.
I think the product I used on the inside of the van was Durabak. It was good stuff for sure and easy to apply with roller and brush. It's a urethane and it's pretty pricey.
You can probably do some research and find tech data on the materials...I'm sure you want this to be a long term solution. If the EPDM website is honest, it's going to last longer than a urethane product. I've had two spare in urethane liners in trucks and they always chipped due to contact damage.
If you do consider a urethane based product, I found lots of positive things about the line-x spray in liner. I know they are a bed liner installer, so I don't know if you can buy it off the shelf.
The other issue I see with a lot of these products is surface prep. I'm envisioning your hut as galvanized steel. Make sure the product will stick to that. Or if painted, it will probably have to buffed--lotta of work there!
Let us know what you find out.

But it looks like good stuff for the job. Just need appropriate protection putting it on.
One of the key features for long term leak proofing is going to be flexibility at low temperatures. I'm no expert on that, but, that's an area I'd be looking at hard.
From what I see, all these products claim great UV durability, but that's a major cause of deterioration. The material in the van is 10 years old and looks new--but, it's not expose to sunlight.
Just google thier name.
Many thanks,

I've got plenty of advice for you. First, I'd like to hear more about you.
What is your favorite month?
I was also looking at insulating it, and then came up with a unique idea:
Don't worry about the seam leaks, just spray-foam the whole top of it. That will fill in the grooves, and make it about three inches above the grooves so that the high spots will also have at least 3" of insulation. When dry, I'll cover with a waterproof membrane. Then felt, then another liner. Lastly, I plan on planting a green roof on it. There are new materials out there that can make it quite thin (so I don't need a ton of dirt on it). Just look up "green walls" on google to get an idea.
It'll look great when done! No more leakage, fully insulated OUTSIDE without taking up any room inside, and green at the same time. Just an idea....
