Hymer Starline BM 640 1999 serial 13991714
I am trying to identify the bumper plastic of the above vehicle since I have, um, inadvertently modified it! I am thinking that it is ABS, but surprisingly I can find no identification marks on the part and various sources suggest PUR. However the cheeks are spot welded to the main part and a soldering iron will melt not burn the plastic which suggests otherwise. Polyester filler will not adhere. Bumper core colour is white along fracture line and all exterior surfaces grey - I suspect it might be self-coloured since sanding does not reveal a white substrate The thickness is about about 4mm. The bumper is a single moulding apart from the lateral edge trims/cheeks
I am also advised that this part is still available from Hymer to special order albeit at some £900. That is both impressive and remarkable but I feel obliged to try repairing first.
TIA
