Silicone on roof rack bolts during installation?

On April 8th, I have an appointment with my local tuner to flash the OTT Tune onto my 6th Gen 4Runner (and 5th Gen to show ol' girl some love), and maybe my Tacoma TRD Pro. I was sending him emails back and forth and I am very excited to get it done and see how it is for both vehicles and maybe my 4th Gen Tacoma as well. I am hesitant about the Tacoma becuase it is a lease and it is a hybrid. But their numbers and reputation with the last-generation trucks are promising. The new 4Runner already drives so much better than the 5th and I assume with this new tune it will be even better with the added horsepower and torque. The nice thing about this tune is that it can easily be removed from the vehicle if needed, without leaving a trace on the ECU. Here is a chart he provided me to show their proven dyno numbers both non-hybrid and hybrid models. Anything I should be cautious about? Non Hybrid Hybrid

I would usually put a silicone on under the bolts during installation but I noticed the 4G taco has an OEM tape around the holes that seems to seal everything when tightened down.. anyone else know what I’m talking about? Should I take it back apart and add some?
