I've thought about looking for waterproof contact paper to "pretty-up" 4 gallon buckets, but never cared enough about "pretty" to bother.
When plastic tends to crack under a hand drill, I use a 1/4" spade bit with sharp edges, or, better, use a "craft burning tool" my SO bought for me. I think that melted holes are stronger than drilled holes, since the melted material builds up as a "lip" around the hole.
A big, old soldering iron would work to melt holes in plastic, too.
Or a big iron nail heated in a gas flame.
The 1/4" spade bit is a GREAT shape for drilling plastic: it whittles rather than scrapes. I have not tried the other style of "spade" bits on plastic.
