Use a lot of spray and keep a towel handy; if you're getting hte full body kit, it comes with 2 bottle spray; use both bottles! The more liquid you use, the less bubbles you'll have. Just be sure to soak the spray with a towel as you squeegee it. Also more spray means it's easier to slide. Finally if you owned a IS previously for the MBP, it used to come in multiple pieces, the palm rest was only covered on the left and right side, not the area top and below the touchpad; the back the area near the vents were not protected. The updated one is all one piece for the bottom (well separate pieces for the battery and memory cover) You'll want to be careful with the fluid as it covers the sides as well.
Finally, I would recommend a getting a PowerSupport Trackpad film instead of using the IS, since it's really grippy, so you want something smooth like the PS Trackpad film.
And those wondering about temperature, my computer is a about 3 degrees Celsius hotter, but it also doesnt overheat anymore. I guess the SHIELD insulates the computer so it forces the heat to be expelled by the fans rather than dissipate and heat up the table, the rest of the computer, and everything.
Grippy gloss:
It covers around the latch button:
Almost seemless fitting of each piece:
Doesn't cover the feet, but gets close to the port to protect it:
Leaves slots and screws exposed while offering maximum protection:
Yes it's that grippy:
I didn't add pictures for the Touchpad because like I said I'm using a PowerSupport Trackpad film; also for the wrist area, I'm using a Moshi Palmguard (which the invisibleSHIELD is identical to except the former is hard, non-glossy, textured, matching; and the latter is glossy and grippy.
