Previously I mounted my first set of reg tags with 3M 5200.
This year it was time to renew, and I did not have any 3M 5200 laying around.
Plus I could not see paying $12 or $16 for some, particularly when the reg tag was only $14.
Unfortunately, I got a hole in my Inflatable SUP.
I ordered a patch kit out of China on the cheap.
It came with some 30 ml of some chemical concoction -- vinyl glue,
claiming to be MEK and urethane or whatever
( perhaps the China equivalent to HH-66 ? )
and not only did it work great for applying the pvc patch material that came in the kit,
it was right handy for gluing my new reg tags for the SIB on top of the old ones....
