What contact cement did you use?  I have glued Velcro to minicell and to the
epoxy-coated wooden surface of my stitch-and-glue and used it successfully for
over three years.  I've also contact-cemented Velcro to Hypalon, and used it
for over a year with no failures.

I used the solvent-based version of Weldwood Contact Cement (not the
water-based version, which others say is inferior).

I am very puzzled why you experienced a failure, unless it is the cement you
used, or some other variable not mentioned -- surface preparation, for
example.  Nylon fabric (the usual backing for Velcro) is notoriously resistant
to contact adhesives.  I sand it well with 80 grit and then clean it with
lacquer thinner before contact cementing.
