A rod has three measurements:

Diameter:  1/2"
Length:  16"
Wire size:  #30

All of these are critical to getting good results.

You didn't put down enough coating liquid.  The key is paper margins and
using a rod that has the right specs.  You want at least an inch of paper on
each side beyond where you want to finally cut the image and a minimum of 3
inches at the top to lay down your rod and then puddle the liquid.  I also
like to have a minimum of 1 inch at the bottom too.  I want the wire on my
rod to be at least two inches more than the coating dimension.  So if I want
a finished 8x10 my paper needs to be a minimum of 10x14 and my rod needs to
have 12" of wire (probably a 16" rod).  I use a #30 because it works with
the viscosity of my coatings and gives me the amount of gloss and leveling
that I want in one coat.  When I'm coating a lot of prints I frequently gang
two prints together and coat them together...this saves paper...only
requiring one 3 inch edge for two prints...I will then sometimes put an
extra bead of liquid half way down between the prints to make sure that I
don't run out on the second print...this works great.  For large
prints...you need more paper at the top because you need to put down more
liquid.  For a 16x20 I work on a 24x24 piece of paper.  In the end, the
biggest cost to coating is the price of extra paper.  I've also found that I
needed to adjust my print sizes to work within the confines of the usual
paper sizes.  For instance when I'm printing 35mm full frame images I print
at 6x9 and can easily get two on an 11x17.
