Re: The good and the bad types of silicone.

Great write up mike. so....i trust that all the silicone products meguiars makes for my tires are safe and won't dry them out? Also, in my search for the right tire dressing I have found that most of them I have tried do leave a brown color on the tire that is very difficult to clean off. what causes that?

ps will be buying meguiars hyper dressing soon!

The brown colour is an effect known as 'browning' and is usually a symptom of a tire that hasn't been cleaned thoroughly. Get in there with a brush and scrub. That's my best advice.

See page 2 of this thread...

Will some tire cleaner/foams/dressings dry rot your tires?

Re: The good and the bad types of silicone.

i had a bad experience with meguiars leather cleaner and conditioner. i applied it to a mercedez black leather interior and it seemed that the silicone in it hazed the leather, luckily i only did one seat and quickly removed it with apc and hot water.

Just to ensure this thread / post does not go in the wrong direction...

To blame "silicone" is a pretty powerful statement, see all above posts

A better way to for all to receive your post is....you had undesirable results with one of our leather products, so you removed it and corrected it with apc & hot water.

We know there are times when a product may not work as expected, and we also know we will not satisfy everyone all the time, but our goal on MOL is to make sure good information is spread.

The brown color is not being left behind by the tire dressing, that is actually antiozonants being released from the tire by design.

In the tire industry it is referred to as "blooming".

Re: The good and the bad types of silicone.

"Blooming" seems to be more noticeable on some brands of tires than others and can also be effected by amount of exposure to harsh sun and/or amount of use. Recently with my own vehicles I had one with an extremely high degree of "blooming" or "browning" of the sidewalls. All the cars had different a different brand of tire: Michelin, Falken, BFGoodrich and Continental. All tires were cleaned the same way (APC diluted 10:1) and treated with the exact same tire dressing (Hot Shine Tire Coating). Only the Michelin tires exhibited the browning of the sidewalls - a dead giveaway that the tire dressing was not the cause.

So what does this mean? probably not a good thing? what does one do to stop the blooming?

Re: The good and the bad types of silicone.

ok just read pg 2. makes sense..you gotta clean your tires well! thats another problem....hard to find a cleaner to clean that old tire shine off completely without the soap getting flat and old tire shine smearing and spreading all over. Although, I have yet to try any of the meguiars detail line cleaners.
