you ever have one of those times when you can stand flat footed looking down and see what you want to do but have no way to reach it. getting the flap on the corner glass has proved to be one of those things. you need to spread the glue on the sill and the flap. but no one has invented a brush with a crooked handle on it. my guess is this got done before the glass went in. the first time it was done. we got it but man it was not pretty now if I just figure out how to seat the trim screws. a bit on the 1/4 in ratchet was how I got them out so that how they go back in.
