My interesting three year experiment with 303 Aerospace Protectant
 

I've used 303 Aerospace Protectant on the rubber and plastic trim (and tires) on my cars for years.

I like it because it doesn't make things to shiny/greasy (like Armorall). And, they claim that it has UV protectant.

I will say, the rubber and plastic trim on my cars never seems to age, for years or decades. Is that because of the 303? Can it really prevent sun damage?

So I decided to do an experiment. On 80s BMW, the "chrome" windshield and rear window "lock strip" trim is actually plastic "chrome," covered by clear plastic.

It is infamous for discoloring with a few years of use, first going to brown, then to completely black - like this

I took a brand new piece of that trim and nailed it to a board.

On half of it, I applied 303. The other half, left bare.

Then I put it on the roof of my house, exposed to the elements 24/7.

I reapplied the 303 occasionally, every 3-4 weeks.

FOR THREE YEARS!

The results have been pretty surprising. I'll pull it down tonight and post pictures.

I use it too! Anxious to see your experiment results.

This tickles my fancy. I've been using 303 ASP for more than 6 years, but I should apply more often (I apply once every 6 months and love it).

Anxious to see the results!

What a tease! Is this click bait? ;)

That's a crazy commitment to a test, dude. Props!

I'm gonna order the second one FREE....just gotta pay the s&h ;)

Now lemme get this straight.....you crawled up to yer roof 30+ times for this?

I just don't know McLovin...

Cool, thanks for the test.

Mebbe he lives next door to the Playboy Mansion or a sorority house.

That's still quite a commitment.

Interested in the results, as well.

Switched from armorall to 303+ some time ago. So, among the waiting...

I’ve been using 303 regularly on my 2004 daily BMW since the day I bought it (original owner). The rubber window trim is still soft and flexible, looks virtually new. I live in Phoenix.

Consumer Reports for the automotive DIY world. Cool.

(I've also done those tests with multiple products whenever I run out of something halfway through, but can never remember which is which ;) )

Can’t wait for the results! I use 303 on my boat and also vehicle rubber and convertible tops.

@motion - I'm a very patient man! Seriously, I wanted to see if my years of religiously putting this stuff on all of my cars' plastic, rubber, trim, emblems, etc. was worth the time and money.

@KC911 - I'm able to get to it by just reaching, without a ladder, etc. (But I still had to do it regularly for three years!)

Without further ado, here's the results:

Wow!!!

It's amazing how well it protected against aging.

After 3 years of rain, sun, wind, etc., on a roof, 24/7, the treated side still looks brand new.

The other side, not so much!

:eek::eek::eek::eek: all I can say is WOW!!! Well color me surprised!!!!

I'm glad I've been 303 ASP for so long already. Thank you for running this experiment for three years, I'm really glad to see it really works so well.

I also switched to 303 years ago. Glad to see there is something to all the hype.

I'm way to lazy....I just don't park my Carrera on the roof ;)

....but nice results!

To cop a phrase from The Ridiculous 6... "That's some mystical ****"
I have been using 303 on the smile, bumper boobs, chin, dash, and window seal for several years now. Good stuff.
