Thanks for your response.
Just to clarify is all the rubber that i am likely to make contact with using a high pressure spray gun resistant to oil on undreside?
Could you give me the chemical specification of this rubber.
For example, does it contain trifluoropropyl groups as some silicone rubbers aren't that resistent. My concern is that this is a new car.
yes all rubber is resistant
no I cannot give you chemical specifications, BMW does not provide this type of detail
personally I would not use any kind of undercoating whatsoever, its a waste of time and money, but you can if you want without worry of the rubber on the car.
Please do not forget to click a positive rating, thanks.
