Not a dumb question.
I have got the name of my school down both sides of the tubes in self adhesive vinyl lettering that I had made at a sign shop. Very easy to apply, and so long as you clean the tubes well and check that they are 100% dry and grease/dirt free, they stay on well.
I have had the lettering on for 2 years now and it is still there. Make sure though that the sign shop uses a thinner vinyl that sticks to the contours better on the pvc or hypol.
I have to deflate and roll up my Zodiac each winter, and feared any lettering would fail. So, black, permanent magic marker. Not real professional, but it works. I redo the letters once or twice a summer; fast, easy, cheap, wrinkle-proof. john
