I don't see any difference from Armor All. It definitely did not make my trim look new or improved at all. Does anyone have any other suggestions?

The purpose of 303 is to provide UV protection and light conditioning for plastic, vinyl and rubber parts. It is specifically designed not to change the appearance of the parts for those trying to maintain a factory look and it will help maintain the new appearance if used regularly.

Can you describe or post pictures of the areas you're having trouble with?

For interior trim, I've been using Lexol's Vinylex. Adds a bit of shine, but it's not greasy and doesn't attract dust like Armor All products used to. This stuff is excellent for the interior and has bailed me out countless times at the concours to cover up "sins". However, it is not meant for outside use since one rain or one car wash and it's gone. It's got great UV protection for interior surfaces that bake in the sun.

For exterior trim, I use One Grand's Exterior Rubber and Vinyl. Great durability outside and after multiple applications (like a dozen over a few months) it'll turn trim back to black and keep it that way. Great for tires too if you like a bit of gloss (but not the Used Car Lot tire look).

I get my stuff from Larry at Car Care Online, though this stuff is readily available from other sources.

RE the 303 -
I've used it for almost a decade on boats and cars.
Have nothing but positive results.
Sometimes on very oxidized hard rubber, it takes several applications and some moderate pressure to clean off the surface. The end product is an original look - not that shoe-polish shine you get with a lot of others.
I use it primarily on seals, tires etc.
For an interior vinyl cleaner / restorer try something else. 303 is really more of a preservative IMHO.

303 make a cleaner as well.

+1 for 303 outside and Lexol Vinylex inside.

Marine Blue

For reference I use Griots Vinyl/Rubber Conditioner inside and out.

if the trim is already oxidized and affected by UV, no magic treatment can roll back that chemical process.

Yes, get protectant on the trim and re-apply after every wash. BTW, a p-dealer SA offered to give my car the trim(SPA) treatment recently for "only" $300. I purchased a spray bottle of 303 for $12 instead and DIY'd for 15-20min.

Thanks everyone. I was speaking of the black window trim around the back window specifically. That's what I tried it on first. Not looking to be shiny, but assumed wrongly that it would help remove that subtle white oxidation. I really appreciate the feedback and will try to do it a couple more times and see if it gets better.

Try this - use a piece of an old white cotton tshirt as a rag. Wet with 303 and scrub the outer window seals using moderate pressure (a little less than you'd use to wipe your windshield). You should get some black residue on the cloth. Next, wipe dry with a glean part of the rag. Then generously reapply the 303, again with a clean part of the rag. Let it soak in. Do a final pass 10 minutes later with the just damp with 303.

I wouldn't recommend this technique for the (much softer) foam door seals. Don't scrub those. Just apply, wipe, reapply on those.

Hope this helps.

If nothing else works, try Back to Black or Black Again....I've used it on other vehicles plastic that was discolored or faded...worked well.

+1. Experienced similar results with Back to Black.

Try Black WOW! Expensive stuff, but you don't use much. Detailers Domain sells it, and you can get the Rennlist discount.

The 303 is a great product. If it ain't leather, I use 303 on it (plastic, vinyl, headliner, etc.). Great tire dressing, too.
