Did I just do a stupid thing with my fan install?

I don't know what's wrong with me, but somehow in rereading the fan install thread,-- after a month away working on a rental property -- I missed the butyl tape part.

Could not get an AC gasket for reasonable price, so made one out of an old truck inner tube, layered that with dicor so it goes fiberglass, dicor, rubber, dicor, fan flange.

Is this ok or am I an idiot?

I did check that my dicor was ok with rubber and fg.

    Not at all. The Dicor will do the job just fine - there's no reason to use anything else. You didn't even need to make the gasket.
    I installed two FF on our last TT with just dicor (didn't use the flimsy bubble wrap "gasket" they provided) and it was still water tight 13 years later.
    On our new trailer they were installed by the factory the same way, just Dicor.

    I would cover the edge of the inner-tube material with Dicor because it will brake down with UV if you dont protect it.

    Two answers.
    1: If it leaks in the first rain you experience... YES you are an idiot.

    However

    2: IF it works.. NO you are an engineer and that is what I think you are.
