magnets

Was noodling thoughts about the magnets.
The equivalent tensile holding power should approach what the common fasteners would have had.Say,that of 3,grade-8,10mm bolts,up into the cast-in-place riv-nuts on the spoiler's underside.
You'd have no protection against shearing forces though.If the foil had any resonance,she could try and walk right off the back of the car.(Frank Lee's 18-wheeler bow and stern blast).
You could have a lanyard on it like the Dodge Daytona Charger,so it couldn't get away from you.
Seems like the liability would outweigh the convenience of no body penetrations.
It scares me just thinking about it.I myself would chicken out.

An alternative might be finger clamps that grip the edges of the decklid (or hatch).

Does the spoiler have to be removable?

I like removability because I want to be able to test it. I want to be able to take it off and put it back on with ease for A-B-A-B testing and such. Also, built to be removable means I can change the mounting configuration at will, without worrying about holes in the decklid. Take a look in the design/build thread and you will see the current version. Holds well using neodymium magnets. Removable in under 10 seconds.
