Skylight/roof repair

I had a problem with the skylight in the shower of my travel trailer leaking I had used dicor twice previously and was very careful with the application of the caulking.
It still leaked.
I live in rainy Oregon and camp year around so I wasn't going to park it with a blue tarp on it....lol.
So I bought a qt of liquid Flex Seal (as seen on TV) I dried off the area with a towel and heated and dried it carefully with a hair dryer. I again carefully filled any suspect holes and cracks with Dicor and brushed one coat of the thick coating about 6 inches wide around and up on the perimeter of the plastic skylight.
Success! We have had lots of rain since the repair and it is bone dry inside.
I am a believer!

    So, using the Dicor you covered 6 inches, the same girth as you did with flexseal?
    Did you dicore over the screws too?
    I can't imagine Dicore Lap sealant not working. I suspect user error, so curious what your method was.
    Dicore is good for RVs since it is a good idea to re-do this every few years anyway. Dicore is easy to remove and re-apply.
    Sounds like by a few years the flexseal will deteriorate so can be cleaned away with a small wisk broom at least.


    I covered the area thoroughly I know what I am doing, I spent 50 years in commercial construction.
    The issue with the Dicor for this job in my opinion is the small hairline cracks and fissures that happen after application and I doesn't "flow" into those small spaces like a liquid.
    Thanks for your upbeat post.

    In rainy Oregon UV may not be a problem..




    Use Henry 887 instead.
