Hy Holger, The Polyester 2 part glue i use on chassis and body,s for repair or modifying.[ i just repaired a fly chassis with it. the chassis was cracked through, nearly all the way across the centre. and didn,t have any strenghthening ribs on it. it was a big ask, but i drilled a small hole at the end of the crack, glued it and layed it on teflon paper to set. after 36 hours i cleaned the excess off the top and its better than new. you can take the chassis and flex it all you want and it wont crack again in the same place. i only discovered it by accident in my quest for glues, that would actually bond the funny plastic they use for bodies and chassis. thats stronger than the surounding area.] the glue doesn,t have a name. its just for automotive use. its 2 part. 1 red and 1 green tube. the ebay name is Suliwenshop or the shop is called Breezilybiz. It costs £1+0.99P&P from china. john
