What properties has the SS 300x got?

I've been thinking (dangerous) about some of the advantages of the SS body.
"anchoring" something to this relatively "smooth" shape e.g. a mirror for towing, tent add-on, may be difficult.
So if it is magnetic enough it would be very handy.
Does anyone know if the 300x SS is able to hold a magnetic anchor point? I have some very strong neodymium magnets that I find useful.
