I did not find that it really wicked at all. To me, it is just a more runny RTV silicone sealant. Because is thinner, it will flow somewhat into nooks better than you can squeeze normal silicone sealant yourself. This, overall, seems to contribute to a better seal, so it might be the best product for the application, but it is not anywhere as great as the description might lead you to believe. Also, because it is runny, it is better used on small gaps and where the application is horizontal. If at an angle or vertical, it will tend to run out and drip. You might be better off with two light applications based on this. Based on its performance to claims, I'd give it a bit under 4 stars.
One problem that this product (and most Permatex products) has is that it comes with a cut-off nozzle to apply the sealant. After you are done, there is no way to seal up the tube. Unfortunately, this makes it more of a one-time-use product and not so good if you want/need to do multiple applications because you still have a leak and/or the product leaked/ran out. I sealed the tip up extremely well with electrical tape, and it barely lasted overnight. (I had to cut some more of the tube off). Some other products (GE, I think) have a replaceable, screw cap over a pointed nozzle which would be much better. This probably knocks it down to 3 stars since it is not that cheap and not widely available.
Finally, it claims to be odor-free. While it is vastly better than the pungent smell of acetic acid, it is not odor-free, but not really bad at all. Very-low odor would be more accurate, although smell is lesser important to me, I round back up to 4 stars.
See my customer image of some landscape lights I was trying to seal from irrigation spray (which keeps corroding/ruining them). You can see that it flows better into crevices, but that it also has a tendency to run out. Hope you find my review useful.
