Thanks, but I usually use Bondo (3M) products.  1 gallon of Evercote
with "tiger hair" (fiberglass fibers) is $196.  The equivalent Bondo
product, without the fur balls is only $60:
<https://www.acehardware.com/departments/automotive-rv-and-marine/auto-tools-and-maintenance/auto-body-repair/8101477>
However, I think a smaller amount (1 quart) will probably be
sufficient.  Obviously, I'll need to run a test to see if the epoxy is
still good.  My Bondo supply is now about 10 years old.

If I really needed the reinforcing, I could add some shredded
fiberglass house insulation or stainless steel wool as filler.  I've
used both on small patch jobs, but not (yet) for auto body work.
