Courtney,

Like Jim Felder, I use the Thetford Campa-Chem and don't use nearly as much
as the bottle calls for.  They have 2 versions -- one with Formaldehyde and
one without, which is more expensive.  I didn't see a difference in
performance between the two.  Have not heard of the stuff that puts a slick
coating on the bowl so can not speak to that, but have never wished for
something that would do that.
