Anti squeal paste on the back of the pads

[Steelepuls]

First time changing the pads on my 01 S, but not the first set of pads I’ve installed on a car. Does any one use the antisqueal paste provided by the pad mfr? The Pelican DIY video does not show the use of the paste. I’m used to putting them on my other cars and wondered if this is not needed on the boxster.

Is the backing pads sufficient?

Sorry if this has been asked. And thanks in advance.
