Sno-Seal is wax with solvent drivers. When the solvents leave the pores it leaves through are wide open to water. In the kind of tests we put boots through they will last a day or two before the wate rstarts getting into the leather and allowing it to stretch.
Once the stretching starts the leather exponentially starts sucking more water and in short order you end up with boots too heavy to walk in and dangerously loose if you really need to stay attached to the ground.
In short, for most people that do hunt in the rainforest, Sno-Seal is OK. For serious use it is not acceptable. If you have a boot drier and a good dry place to work your boot sover nightly that also works with the Sno-Seal. Not an option in any camp I have hunted in though...
Now the good news is that Sno-Seal is just wax with solvents added to make application easy. Melt plain beeswax into the leather and the solvent pores do not form and the leather does not absorb and stretch. The beeswax lasts much longer and the waxed leather reduces abrasion by a phenomenal margin.
So the pluses are application ease at the expense of water proofness and staying so...
