When I say do not use the Rutan airfoils I was talking about the canard (forgot to mention that). At these exponentially low renolds numbers I agree that the main wing airfoil wont make much difference between the Rutan (Modified Eppler 1230) and the Clark Y. (I'd use a regular 1230 cos it's easy to the Coords and looks cooler)

I do not know if you have seen the 1145 but it has a very blunt LE and not a great deal of camber. It was created because the original GU25 (the first canard foil) did lose lift with water or bugs (any imperfection) on the canard. (as you said)

The GU25 is almost flat bottom but has a wierd camber that is almost at 50% chord. A funny looking foil. Both of these are very different than any foil I have seen used on models.
