I've seen threads where it was implied that paint and Eternabond don't work well together. I have a 73 Holiday Rambler - Aluminum roof (nice!) but some of the white has gone away. (I have a large grey patch of aluminum just soaking up the sun!) So I need to paint the roof, and I plan to paint the whole roof with a product like KoolSeal. The seams were pretty bad, someone tried using Henry's on it, so that's all coming off. And there's a good amount of SilverSeal still hanging out (original roof sealant, I believe), so I'm trying to scrape that off or at least smooth it out. I'm not aware of leaks, but I have trouble believing it based on the condition of the sealing at the seams. (The SoCal drought does have its up side.) So once I get the seams cleaned out and acetone the heck out of them, I expect to EternaBond.

Question is, do I KoolSeal first then EternaBond, or EternaBond then KoolSeal? I like the second idea better, just for the aesthetic of a single uniform color and finish up there. I'd even be happy if I could paint just over the edge of the EB, especially on the roof inside the seam. But if painting or coating the tape has a detrimental effect on its longevity then I may reconsider my options.

So wondering what experience people have coating their roofs after EternaBond, or is it better to paint the roof (including the seams where I expect to tape) before applying the EternaBond? Just don't want to do a helluva lot of work to set myself up for a later failure.

Contact Eternabomd customer service. They were great when I had questions about using their product on my TPO roof.

micalk-

No personal experience- but I used to own a Lazy Daze, and their user group has a lot of experience. Here's a link to the Lazy Daze Companion articles on Eternabond.

I suspect it's better to apply Eternabond to bare metal and then paint. But what do I know? ;-)

You might find your answer in the Eternabond video library.
There are videos showing us how to apply Eternabond correctly in most every situation.

Note that Eternabond makes a number of different tape products and some may be more readily paintable than others. The usual stuff with the shiny (TPO, I think) skin might need priming to get anything to stick to it. I think the Eternabond product recommended if you plan to over-coat is named Webseal.

Thanks, Gary. I came to the same conclusion about webseal. And so that answered my other question about which to apply first. But now my paint question is... Do I need to prime any bare aluminum or can the Dicor Metal RV Roof Coating be applied without primer? Most of my roof paint is sound on the large flat areas, but there are bare spots. For regular paint I know you apply primer first but I'm not sure about this. Dicor website doesn't say, and I just sent them an email to ask.
