Thanks for the results. The guy who turned me on to the stuff used it on his boat...

Nice, thanks for posting this.

Used this stuff for years.

I apply it on all rubber, tires,vinyl,leather after cleaning and conditioning. The stuff is a godsend!http://forums.pelicanparts.com/uploa...1517619741.jpg

You should email this thread to the 303 people.
You should also post your photos on other car forums.

Why don't you do the same test on a piece of rubber ?

Wow! Impressive results. Costs a little more, but well worth it. I'd like to see how well it protects that *****ty interior plastic that BMW uses that turns to dust after a few years in the sun!

(Hmm, I wonder if it will work on my skin!)

Very valuable, great test, I've been doing the same thing with Cerakote in terms of UV stability. Black in a south facing window for over a year has done nothing to it.

What I want to know is what will either restore, slow down or arrest plastic degradation like on a 911 dash. I am restoring a 76 Carrera 3.0 with a crack free 1 year only dash. Amazon has 10 different automotive plastic conditioners.

Which one will actually work?

I’m thinking of mixing a little in in my smoothies!

..?

Will this stuff work on polycarbonate windows? I have two cars that have polycarbonate roof panels and also rear quarterlight windows. And what about plastic headlamp lenses?

I've never heard of this stuff but will now start using it in place of the other stuff I have been using. Thanks for the test.

Is 303 readily available at most FLAPS? Or is that a special order somewhere?

Never heard of the stuff either. I just ordered some, including their leather product.

Thanks!

According to Google, you can order it at Walmart.com or Amazon.com among others

I've head about 303 in the tech forum and bought one. You have inspired me to test, but I will compare it to Mother's Protectant, which is what I have been using before... Maybe just 1 month. I don't think I can do 3 years.

It's not oily/greasy/sticky once applied is it?

I hate getting a car detailed and then getting it back and the steering wheel and interior looks like it's got a thick coat of oil that gets on your hands and attracts dust and stuff.

I just get it on Amazon.

It's not oily/greasy, Imo it's perfect sheen for exterior things. i do use it more sparingly on the interior, but i prefer a drier, lower sheen interior than most.

I think it would great on polycarbonate windows. I've been using it in my 2007 BMW plastic headlights for 9 years, they are still crystal clear. I use it on all the lenses, emblems, etc. Pretty much all unpainted exterior things.

A 1 month test won't show anything. It took over a year before I started noticing anything.

This is all good to hear. I am in Texas, but fortunately, my car is in a garage at home and at work so it gets very little sun time, but still, some protection would be nice.

Also, +1000 on the dry, low sheen interior!

I actually learned about it at the aerospace company that I used to work at. Our flight mechanics used it on the canopy on the T-6.

I'd like to give this stuff a go. I can buy it locally at a car parts store.

Meanwhile, this is an excellent video (if you can get past his ascent and tattoos) of how 303 is used on leather. The use of 303 starts at 11 minutes.

For leather I would rate Leatherique as better than 303. 303 is better on vinyl.
