Ok so there is a point of first contact after which the object begins
"growing" into the stationary frame. What happens after the point of first
contact doesn't shift the point of first contact.

The word "contact" is the problem because if you are in different frames the 
point of contact is actually a collision especially so if you are talking 
relativistic  vs stationary and the "angle of incidence" includes  an object 
shrinking away from the luminal frame while growing into the stationary frame 
... theres gonna be sparks :_)

Both frames are in sliding contact so it takes no time for the sprayer to leave 
behind a mark.
I suspect there is a (hidden?) assumption in relativity theory that does not 
allow for instant communication at the sliding interface between two frames of 
reference.

Special Relativity has a real problem with instantaneous communication,
even when it must be possible as in this case.

leave behind a mark.
I suspect there is a (hidden?) assumption in relativity theory that does
not allow for instant communication at the sliding interface between two
frames of reference.

I would think there is a Lorentzian conversion of the paint going from a near C 
frame to a stationary frame.. the tracks will appear  further away from the 
under carridge because the train is  displaced /shrinking away from the axis of 
spatial displacement  at an angle between time and the spatial vector. Never 
able to reach C from our perspective just get smaller and “slower” once past 45 
degrees.
