Stop. 303 has no business on belts - nor does any dressing or "protectant". 303 has silicones in it - and it will poison an O2 or A/F sensor - airborne silicones can enter an O2 sensor and coat the sensing element with silica and kill it. 303 is good stuff for the interior and exterior trim.

How is silicones from a belt going to get into the air system and affect the MAF / 02 sensors with a filter in place and usually a cold air pick-up away from the belt area. Also this system is sealed otherwise...

that grey film on the inside of the windshield? its the result of silicone hitting rubber and releasing.... from the rubber which i can't remember. In other words, silicone feels good and looks pretty but promotes a breakdown in the rubber. Not a fan.
Rubber is not what structurally does the work in belts anyway.
This is really well-intended but mis-placed TLC.

I thought the film on the inside of the windshield was the off-gasing of the dashboard.
Quick google revealed this because I can't remember where I read this originally...

The film you see is created by all the plastic that's inside your car. When your car is out in the sun, the sun heats up the interior to 130-145F or so. This heat creates off-gassing of the plastic dashboard and all other components. The plastic molecules get into the air and then settle on the glass surfaces.

It is mostly water with some PDMS. Friction is important to belts and having silicone on your belts may cause slippage.

My freshly changed accessory belt(and tensioner pulley) was squealing in the rain. Every time. A small splash of silicone spray fixed it. As silicone is derived from silica, itself a major constituent of tire rubber, I fail to see how it could hurt anything. Seems to add durability and grip(winter) under extreme conditions. Go for it.
per nokiantyre
Why is silica added to Tyres?
The compound provides the tyre with winter grip under extreme conditions, as well as wear resistance and wet grip. The mixture of natural rubber and silica give the winter tyre very good wear resistance. ... Silica is used as a bonding agent in the tyre instead of carbon black.

Is this the same guy that kept posting weird things. Drove around on a rim then when he was banned he kept coming back with a new name?
I wouldn't put it on a drive belt.... but I do put it on the tires of infrequently used things I own. Trailers, the pickup. And the dashboards and all interior plastics of my vehicles.

O2 sensors also take in ambient air and the O2 difference between ambient air and the exhaust stream changes the voltage the sensor outputs. That's why you see the tiny holes on the body of an O2S/AFS - they are more prominent on Denso/NTK sensors since there's a Teflon or Gore-Tex filter that's visible from the top holes. https://en.wikipedia.org/wiki/Oxygen_sensor
But still, it's a good idea to keep silicones away from a O2S/AFS.

I'm afraid ...± not. The only thing I have ever been banned from was a Baptist church about 25 years ago. But that's a long story that I won't bore you with.
You do make an interesting point. I would venture to say the general public thinks most anyone on this forum is a little weird.
We argue over engine oils and OCIs. Really?

What a great idea- you are smarter than the engineers at Gates, Dayco , Bando etc. Belts depend on friction to drive the accessory,
by putting anything on them you are defeating the purpose

I would not do it, simply because I have no problem at all with the very good lifespan I see from belts and tires. I would be more concerned about possible adverse effects of doing this, vs any extended life of the rubber items.

I'm a suspenders man myself, haven't used a belt since the late 90s
I have heard of this here on Bitog some time ago but I don't feel the need to try it. With EPDM rubber I cant see it bringing much of anything anyway.
