i use a 2 part polyester resin glue i bought of ebay, the only drawback is its not instant, takes3 mins to grab and 9 mins to cure, high strength wonderfull for repairing bodies and for adding plasticard-polystyrene to original bodies. it cost about £2.50 all in. its all in chinese on the small tubes. but if any ones interested, i,ll look it up and post for you. amost forgot to ask!does it  fog up the clear windows, with its fumes. john.
