Very interesting. I'm going to try it.
NEVER REPLACE WIPER BLADES AGAIN
I use 303 on just about everything plastic and rubber including my tires and wiper blades, but not on any really consistent interval, but when I think of it. If you keep any vehicle for a long time treating all the gaskets and giving any plastic under the hood including any rubber hoses a good spray with 303 is IMO good and cheap insurance.
I always keep a gallon of the stuff around. I also keep an old heavy cotton "athletic type" sock stored over my 303 bottle that I use like a glove for 303 applications. Once soaked even when dried out get soaked in 303 the next time a lot quicker and saves a little 303 over the long haul.
I also use the sock applicator over the scrubber type pole shown below to apply the 303 on my awning which makes putting in on that much easier since you can do the entire awning top from the ground by simply rolling the awning out and not raising it and then using the sock applicator to spread the 303 out over the entire awning.

I know a lot of folks recommend using it on the trailer decals, but I have been using Meguairs Ultimate Wax for the last 11 years with great success and like it since it will last much longer than 303 which to be effective needs to be reapplied about every 2 months or so if exposed to the weather directly.
