What does the verbiage in the plans call out for??
I always look for the "Sensor Safe" RTV.
The regular stuff has a strong vinegar smell. That smell is acetic acid which does not play nicely with aluminum.
Are you looking for the stuff that 'glues' the trailing edge? If so, I don't think this is it. This is silicone gasket material and won't provide any strength at all. I bought the same stuff but ended up not using it. I used the 2 part epoxy type version from Aircraft Spruce.
YMMV but I am happy how mine turned out.
