I use a vinyl car bra. Its handy to have on long road trips too and during
winter when there's lots of gravel and salt on the roads.
In addition to the bra I tape up the side skirts and and around the
wheel well arches because the r-comps pick up everything and kick it back

The usual blue painter's tape from Home
Despot or Lowes is the choice of most.
The Boxster hood is made of aluminum so the magnetic hood covers
often found at track events won't stay on. You shold be ok with the bra.
Or you could buy a really big broom and sweep up the racing line you would
make lots of friends!
