I rolled on Tropi-cool, there is some texture but it looks good nonetheless. Even if I had an airless that could pump it I would still roll it. That paint turns into rubber pretty quickly. Much easier to throw a roller away than clean a pump and fifty + feet of hose of that stuff.

Keep your weight on the ribs and you won't damage anything or make any dents.
I'd roll it. Its harder to spray up there at those angles.

Thanks Steve.

Would the tape conform to the surface of rivets? Or would it be like a little pocket on top? I'm not sure if my question makes sense, but hopefully it does.

I used Dynatron-550 to create a 1" wide strip over each seam between roof panels, so a half inch on each side of the seam. The rivets are far enough from the seam that they don't come into play.

I understand your question. I am not sure of the answer. I have observed others do it but have not tried it myself. Knock on wood.........

Perhaps one of the folks who have first hand experience will chime in.

We used 6" and 4" Eternabond on all seams and rivets. First we had to remove all of the silicone SOMEONE had put all over the rivets and some seams. The EternaBond does not stick to silicone. The EternaBond will *mostly* adhere tightly to the rivets. You do have to go slow around the rivets and press it in well arounnd them. A few of my first rivets did not get the proper attention as I had not yet learned the technique. They are sealed up, but do show a little pucker.


If I can find pictures of the rivets, I'll post them.

Thanks everyone. Really appreciate all the advice. I'm leaning further & further away from the elastomeric now. New plan is to get everything watertight w/o relying on a 'paint', and then choose the coating based on other factors.

The only other advantage I'm seeing to elastomeric is cooling, and from what I can tell (correct me if I'm wrong) that appears to be a function of color and thickness. I doubt I can put down the same thickness as elastomeric with auto paint, but I think with 2-3 coats of something high-build (in white, of course) I wouldn't be sacrificing a whole lot?

Much of what I'm thinking has been influenced on advice you've given in other related threads

CB is a pretty sharp guy. Maybe we should keep him around?
