Hay i glued my armour with plastic weld same stuff plumbers use to glue plastic pipe together, dont know where you are but BnQ do it in the plumbing section would you belive LOL i did try polly cement even if i sanded the plastic fot the glue to grip it didnt realy help with the fixing.Oh get some clips to hold the parts together i made that mistake. Hope it helps and you i was told also by a friend on here that less is more best thing to do is a troop for the day then you will know what digs in and needs trimming.
Nice AP armour though
