Dave,
I tried the silver Sharpie too, but it faded ( but my plants were in the sun). That's why I use the deco-marker. It's paint, not ink, so is very permanent.
Writing on the pots is so much faster than using labels. Easy to see the information, too- just turn the pot.

The other thing I recently discovered, while repotting and/or potting on
several hundred different plants, was the silver colored ink pen made by
Sharpie. Rather than set plants in groups, thinking that I'll make the
labels shortly (which of us hasn't said THAT), I just wrote on the pot.
The ink (more like paint) seems to be quite permanent, easy to read, and
since I plunge most of my pots in sawdust, won't fade from the sun. I
don't have to worry about stopping work to write labels. I can easily
go back and write labels when I can't be outside or when not so busy.
