Dicor or roof sealant opinions please......
Need to replace the sealant on my cargo trailer's aluminum, riveted rounded corner roof pieces. Looking at using some Dicor self leveling caulking for the job, but have read that some people have had issues with it adhering to aluminium. My guess would be that the prep was the cause of that, but would like to hear some opinions on the product, or other products that would work for the job.

I had my travel trailer roof that looks like aluminum (though I can't say for sure) professionally sealed with Dicor 3 - 4 years ago. It's been fine, so far. I've been told it needs to be done right,

Flexseal! If it'll make a boat with a screen door bottom it should work fine on a junky ol' cargo trailer.

My uncle went for a ride in one of those boats repaired with Flexseal right before he died.

Permatex flowable silicon. Clean what you can reach. This silicon actually flows down into cracks and seals them. Used it on the back side glasses on my bronco Ii. Worked great! Had one spot actually flow thru and fall into the carpet, my fault for adding too much too fast. Now I have a perm spot of silicon in the back floor board carpet to boot! 😁

Followup, NP 1 is the caulk of choice in sealing modern day forced ventilated poultry houses. I know of many houses 15 to 20 years old where the seals are as good as the day it was spread..I assure you it will hold up well.

Reminds of a trailer house we lived in. Had a rolled metal roof and when the wind blew hard you could hear it ripple from one end to the other.
I got up on the roof and would step on either side of the seams, allowing the seam to open up. I then troweled in the seam with fibered black tar.
I then went over the top of the seams with black mesh and more fibered black tar feathering it out well.
Finally brushed the entire roof with fibered aluminum(silver) roof coat.
That roof never leaked and never rippled again.

Your comment in turn reminds me of a friend's story of renting an old house with a bunch of guys during college. The roof leaked so badly that they went to the local builder's supply and bought the biggest tarp they could find - spread it out in the attic. The leaks disappeared for some time. Then one night during one of those big thunderstorms they heard a groaning sound from the attic just before the ceiling collapsed on them from the weight of the water.

What ever you end up using just make it has some flex to it.

The one thing about the Dicor is that you can clean it up and apply more to it if there is a crack or leak w/o removing the base layer. Can you do that with the NP 1 stuff?

Yep sure can . Flexs well ,waterproof and sticks to everything.
