Polurea is much more UV resistant then epoxy. But to clarify this only applies to outdoor situaitons. Even high powered metal halide bulbs don't seem to produce the correct wavelengths and/or intensities of UV to break down epoxy.



Both polyurea and epoxy are strong, but in different ways. Polyurea is much more flexible but both are more than flexible enough. Epoxy resin is flexible enough for use in plywood aquaria and those flex quite a bit.



One other comment I have heard about polyurea in certain applications is that it is hard to clean. But I'm guessing that Repti-Shield is formulated to be easy to clean.



Lastly, I want to stress that spraying polyurea is something that should not be taken lightly. The blends used in truck bed liners and for outdoor fish ponds require some pretty serious equipment and respirators in order to be sprayed efficiently and safely.
