i gotta agree with Andy on all points... having judged numerous contests, there're times when 2-3 3-4 models are in contention, they all have nice paint, good build quality, etc... so, it comes to the underside..seams gone?? detailed?? and on and on...you gotta pick them up!!
i would be EMBARESSED if something fell off one of my builds...i DO like the idea of the elmer's glue tho'...lol
anyway, i think that a judge is gonna handle the model as if it was his/hers anyway[i know I do..]...so, what's the problem??
