I don't wanna hear any smart talk out of you people (especially you, John... you bastard).
The thing about reading the directions, whether it be for Water Effects or a home stereo or nitro glycerine, is that someone usually writes them for a reason. Take, for example, the instruction on both bottles of Water Effects which clearly say that you should layer the water in 1/8" increments. I just sorta said "screw that" and piledrove my way into it. Patience is a virtue... it's just not my virtue.
So the result (predictably) is that there are bubbles everywhere. The Games Workshop product has lots of little ones:
...and the Woodland Scenics' has a few giant ones.
Both of the ponds have a hard-enough surface that popping them is difficult and also leaves a permanent mark (or it would if I didn't fill it with more product after).
Interestingly, the Woodland Scenics product is coming into the lead again. It's easier to do on-the-fly repair work with it (like popping a giant bubble and then refilling the hole with more resin), whereas the GW product tends to tug and ripple when you mess with it in a way that is hard to compensate for.
The battle's not over yet, though.
