The previous owner of my 380sl had the engine bay of my car detailed.At the time this was done the detailer used an aerosol product he called engine "Engine Seal" when he finished cleaning.This product has left a high gloss finish on the hoses.I want to enter this car in some shows and I dont know if points would be deducted for the gloss on the hoses.Does anyone know a method to remove this gloss finish without changing the hoses?
