+xSounds like a cool project. Yes you can brush apply the GlassCast 3 to the legs. You will not be able to brush it too thick as otherwise it will run, however, reapply when the resin gets to the B stage of cure (firm but tacky) and you will be able to build a few layers up relatively quickly. Then you can flat it with sandpaper and polish back to a gloss to get a nice flat and glossy finish.
Thanks warren great advice , I will upload picture before and after , thanks again
