Hello Peter, Glad you have fitted the guards and they look good. Still have to fit mine, but i am not sure whether to fit the later size ie standard like yours , or make myself a set of smaller ones for the 1990 crossflow car, think i will go for the latter. so that could be a new line ! Regarding cleaning, a simple red scotch brite wrapped round a nice 2" x 3" x 1" square block of wood, rubbed up and downn in an even line of draw will restore the look Just be very carefull and dont overun on to your paintwork. You can get some Diamond impregnated blocks ,cant remember the name tonight ,will post up later. They work very well also. Would like a picture if you get a chance Peter, Regards Richard
