I've been using this since 2008 and yes, it really does do what it says on the bottle. It is more expensive but a little goes a long way and it is hands down better than Armor-All or any other so-called "protectant." I use this on my auto dashes, car seats, motorcycle seats, dashboard instruments, and most other black plastic parts on my car/bike. Not only does it give black plastics a deep, dark color, it stays that way for quite some time. If you periodically treat your stuff with 303 it WILL stay looking like new even in the most brutal conditions. It's neither greasy nor shiny so applying it to your car's dashboard will not create high reflectivity on the inside of your windshield on sunny days.

I own a 2013 BMW Mini Cooper and I haven't taken it in for its first service appointment yet, but I sat down with the head mechanic and asked about keeping the engine clean with my regular routine of spraying Simple Green in the entire engine, scrubbing areas with various foam and bristle brushes, then using a nearby water hose with a light trickling of water to clean the engine off, then applying a spraying of 303 Aerospace over the whole bay and let dry for a few hours. The mechanic said it would be much appreciated during servicing, as a clean engine is easier to diagnose and work on, and the dressing helps keep the rubber hoses in the engine from deteriorating, which are usually the things to fail first and need replacing.

I use 303 Aerospace solely as an engine dressing, and while the instructions say to spray on and wipe off after a few minutes, when it comes to engines, clean the engine, and while wet, soak the entire bay with 303 Aerospace. If possible, leave the hood open and let it air dry for a few hours. Close the hood after that and engine cleaning is done!

I have Klasse VLR protectant for my usual treatment of exterior plastic/vinyl areas but when doing the engine, I often go over the car exterior with 303. Can't hurt.

Highly recommend this for engine dressing.

Keep in mind, this will not 'restore' plastic/vinyl to look like new. It'll keep the materials looking the way they do. So if you have a brand new car, start using this and it'll keep the car looking new. If you have faded or worn out areas, it'll keep those areas from getting worse, but won't make it look better. This works as a protectant, but doesn't restore.

For restoration, you'll need to research other products.

I keep this in my auto detailing kit always.

I just bought my fourth gallon, yes, gallon of 303. And I've received tremendous value from the first three over a lot of years.

I use 303 on just about everything in my car that is smooth and not paint (Zaino for the paint.) The door seals are six years old and look perfect. The plastic headlamp lenses are perfect. Tires. Wheels. Trim. Instrument cluster.

My teak outdoor furniture looks great. (Get some big Scotch-Brite pads and 409. Spray the teak liberally with 409, go over with the Scotch-Brite, rinse with a hose, let dry, then treat with 303 Protectant -- you'll be stunned how well it works. Every month or so, a quick spray of 303, then wipe it dry, and you're done.)

I keep 303 around because pretty much anything that has a hard surface (so that you can wipe it dry ... that's key) looks better and lasts longer. I have a carbon fiber frame on my bicycle. 303 keeps it looking perfect.

Every time I work on something, or clean it up, I 303 (for me, it is a verb) it. Rubber soles on shoes. A vacuum cleaner. You name it.

Truly, out of everything I get on Amazon, it is one of the only things I would clearly give six stars to if I could. It keeps my stuff looking good. It restores stuff that is looking worn. I can't recommend it more highly.

This stuff is like a time machine in a bottle. My patio furniture has been brought back from the dead -- it's 1997 all over again.

I have been using 303 and it is the finest product in it's class. Yep, it's still work using any vinyl cleaner, but this one actually keeps working so after that first cleaning, when you first notice the junk at the seams, it just keeps getting easier. It's not slick, low-pleasant odor, doesn't dry up, and keeps out the dirt. Your hands will be silky smooth after using it. It completely replaces Armor-All, the worst of all I have tried. I'm a junkie for a new product, trying to find the best and easiest, but I always have to do it over with 303. Save some money by getting 303 in a small squirt bottle that is easily handled (carried, back pocket,etc.) and then get the gallon as well. You will use a lot of it in the beginning as you find that it works on your leather couch, hot tub cover, outdoor furniture, tires, windshield wipers, dock ropes (A BIGGIE) and just about anything you wish to soften and preserve. I am not sure I have found anything it won't work on and more importantly, anything it has harmed (try Armor-All on your cycle seat some time for a real thrill.) Yes, it can even be used on motorcycle seats and keeps the UV from drying them out. Handgrips, fancy riding suit, gloves (heaven for breaking in a new pair of leather riding gloves) and oh so much more. This is getting long, so let me just say that there is no finer product on the market as a protection product. Works on faded fiberglass and you won't believe your eyes. Just get a bottle and try it. There is a new rotary brush at Amazon in soft bristle that could save a lot of work (have it, haven't tried it.) Work it into places as hard or easy as you want, it still works keeping boat stitches from breaking on seats and canvas tops. It is truly a miracle in a bottle, just like no one would be without WD-40, you never want to be out of 303. 25 years or more of use is in this review. The Captain gives it 5 stars and I'm VERY critical of products.
