Ferromagnetic?

[Homestead]

Is the stainless sides capable of attaching magnetic signs? Do we have to paint our messages on the truck?

We don't know what X is but the 300 series is not, AFIK, ferromagnetic.

Space X capsule would be attracting meteorites then.

Work hardened 3 series stainless can be weakly ferromagnetic. Wouldn't count on a sign sticking though.
A chartible organization I volunteer for had the use of some F-150's for an event. Found out that magnetic signs they had don't stick to aluminum body panels. Nobody thought of that beforehand, LOL.
