CV boot conditioner to extend life...

[RF_Burns]

Before I park the Murray for the winter, I was wondering if there was any way of protecting the CV boots and other rubber boots from drying out and
deteriorating.

I searched on here and found nothing. A google search came up with some products and suggestions such as Armour-All, WD40, silicon sprays etc... but
there was just as many warnings against using these products.

Any experiences? Recommendations?

Thanks.

Bruce,

303 Aerospace UV Protectant was recommended by Bob Sternfels as a conditioner and protection for GMC airbags. Bob was the guy that made the airbag
covers/socks. I use it on almost all exterior rubber and plastic on the coach. Google the stuff and read the Amazon reviews and questions. It's also
highly regarded in collector car circles.

+1 on 303 products... Incidentally, their fabric care products are also recommended by Zip Dee:

I’d venture that since the don’t really get UV, most of the attack comes from the petroleum grease products contained inside of the joint

Ozone does a number on rubber as well... 303 is supposed to protect against ozone degradation... The dry cracking you see on the outside of aged CV
boots is most likely ozone related...

A quick search shows the atmosphere is 0.00006 of a percent ozone, and most of that is up in the ozone layer 20 miles up.

That is correct... Ozone is a very potent oxidizer... Per Wikipedia:

Quote:

> nitrile rubber being most sensitive to degradation

There also tend to be higher levels of ozone near cities and industrial areas... Electric motors, industry, oil and gas production all create higher
levels of ozone near the ground...

I'll also add that CV grease is designed to be compatible with rubber...

No doubt O3 speeds up rubber degradation. The ozone generators that are used to remove smoke odors cause the articles to disintegrate a year later.
But again it’s all about concentrations.

I hope, when I retire, I'll have time to do those things.
I went to Western States with a very dusty non washed coach.
Someone was considerate to hand print , WASH ME Please !
