Great engine dressing
August 19, 2021
This stuff works great after cleaning your engine Spray it on and wipe or blow it to spread then close the hood and run the engine
ProsEasy to use Leaves a nice sheen

I use this on everything but paint and carpet.

Almost every surface of my cars gets 303 on it. Interior, mats, seats, tires, wheel wells, gaskets.... It is a simple easy to use product. It does not last a long time on exterior, maybe 2 weeks, but interior it lasts 2 months of like new look.

Protects Plastics Well
September 29, 2020
Application is easy, not sticky, leaves smooth not greasy or oily surface and seems to help repel dust and renew the plastic with a nice dark coloring (My plastic is black). I just spray towel and wipe on. On more weathered surfaces I spray directly and wipe in. Have been using for 7 years. Have tried other products due to the price, but always return back to this.
ProsHelps repel dust Easy to apply and wipe

What hasn't already been said about 303AP. I use this stuff all around my home, not just for the cars. I also use it on my giant RV tires. I don't necessarily want the RV tires to shine, but they do need strong UV protection. This is the product I use.

I've used 303 protectant for over 20 years. Everything it has been applied to has been well protected.
ProsLeaves a nice clean matte finish on most materials (make sure to remove excess with a microfiber towel before it dries!). Essentially odorless.
ConsCan be a bit slippery on Mercedes MB-tex seating surfaces.

Top notch product. Superb results from an advanced formulation.

Everything I anticipated this product to be. Easy to apply with immediate results. Truly enhances the appearance to applied surfaces.

Best on the market
July 13, 2018
Best product I have found on the market thus far. I formally used a product called "UV2", but it mysteriously disappeared and could no longer be found. This is very close in performance and I have no complaints.
ProsNon-greasy and does not attract dust. Leaves a satin sheen that is very natural looking. Great for rubber, vinyl and plastic.

The Best
July 24, 2016
I have spent a mountain of money trying everything else, and this is the one that all others are compared to. It is the best. Period - end of story. Don't waste a pile of cash like I did. Just buy this product. It is great for natural looking rubber, tonneau covers, interior vinyl and so on. What really attracted me to it initially was how well it protected the dashboard without looking greasy. Later, I used it on the tonneau cover for my pickup truck bed. Did an amazing job even in the harshest of Chicago weather. I recommend this product without reservation. Your search is over. Buy this one.
ProsLong lasting, natural shine, not greasy looking or feeling. Excellent protection.
ConsThey don't give it away for free.

I had originally bought this 303 protectant for my convertible top and it worked awesome. I then gave it a shot on exterior trim panels on my son's suv and it worked better than anything he or I have ever used. Made it look like new but not shiny which is fine. A very good product.
ProsEasy to use No mess

As good as the reviews
January 13, 2016
I used this this weekend on the interior of my Sprinter van. I was expecting good results and got excellent results. Monday morning I was really happy to see the 303 did not cause glare but did make my interior look new. As a bonus my wife put it on the Weather Tech mats and they did not become slippery just new looking. The surfaces were first cleaned with 303 APC.
ProsA little goes a long way with a few sprays on a small micro fiber towel corner. Use the other parts of the towel to buff if you over do a area. I do not believe she used more than 1/2 ounce.
ConsThey should send samples out 10 years ago so I could have used this sooner. This was recommended to me by Ray and it really does a great job.

303 Protectant was the first dressing I buy, after doing a little research online I found many recommendations and decided to try it, I was amazed by the results on my 2014 corvette stingray's interior, it was easy to apply & economical (less is more), it's not shinny, it made the interior look natural and dark just like new & it lasts for about 2 weeks! I highly recommend this product and I always keep a bottle in hand.
ProsEasy to apply Leaves a natural satin finish Perfect for interior, plastic parts, trim and rubber

Great product for Vinyl
October 25, 2014
I'd say it's best used on interior parts and engine compartments. Though I've used it on a vinyl hardtop followed with Sonax BSD to great results.
ProsExcellent on interior and engine compartment vinyls.

This is the best product to clean and protect your vehicles interiors ( also use it under the hood)
October 19, 2014
I thought I would try this product based upon reviews I read about it. This 303 aerospace product is absolutely amazing and I have now used it on all plastic, vinyl and leather in the various vehicles we own. I also used it after I cleaned the engine compartment of my 82 Corvette and the engine compartment looks fantastic.The results are truly amazing and my old corvette has now won two trophies in two different car shows I entered my car in. I have had many people ask me how I got the engine compartment to look so awesome and I have told them 303 Aerospace protectant. I can't find it here locally but I ordered the gallon refill and couldn't be happier with this product and the results I get after using it!
Pros Not too shiny and restores the look of the vinyl, plastic and leather in vehicles. I also use it under the hood (on the engine compartment) and the engines in my vehicles look fantastic after using this product on them.
ConsIt's a little pricey but the results speak for itself as whatever you put this product on looks fantastic afterwards.

I found out about this product a couple years ago and have been using it since. I found it at a business that makes tents and covers etc. This protectant was recommended over another very popular product, Ar****all. I use it on my pontoon vinyl seats etc. You can imagine the beating they get out on the river. The vinyl is so supple after use and repels water.

I finally broke down and bought some of this to try. I thought about trying it out on some customers cars, but ended up using it on my trim on my new truck. I love the sheen it has. Very easy to use. I tried it in the engine compartment on my plastic coverings and it looks very natural.

Aerospace Protectant
July 12, 2013
I've been using this product for at least 10 years, and have been extremely satisfied with its ability to protect "plastics" that are exposed to intense sunlight. I have used it extensively on our cars, and on our cabin cruiser, all of which are exposed most of the summer to intense insolation. We moved recently to a remote location in Wyoming, and could not find Protectant in any of the stores. We were glad to find it on line, and have since recommended it to the local NAPA outlet.

I have used this product for about 13 years now. I have bought and sold several cars during that time. Usually the person who buys a car from me wants to know why the rubber seals are brand new. I tell them I use 303 and they immediately buy some.

303 Aerospace protectant
January 2, 2013
303 Aerospace protectant is the best uv prtectant available on the market, nothing beats its quality. It is long lasting, restore already damaged surface to like new condition. I use it as preventive coating on dashboard, bumpers and in the engine bay. Anything that is plastic or rubber including tires I spray with 303 Ap I have been using 303 Aerospace protctant for years on my cars, and the only product which came close in performance was much cheaper Meguiar's Supreme Shine® .
ProsNumber one protectant on the market Worth to pay extra for its supreme performance Long lasting protection, very efficient excellent surface coverage, easy to apply Non greasy formula applied twice a year and after 5 years dashboard look like new Affordable
ConsHigh price it is not available at your local auto store

303 restored the dash of my 14 year old Corvette's dashboard to a showroom look - not too dull, not too shiny - just right. Since it's not slimy like some products, it's also great to use with a brush to clean out air vents adding to a showroom-new cleaning that won't attract or collect dust. Along with the cars, I treat my boat vinyl seats to keep them looking new.
ProsPerfect sheen

MOST Incredible Product! Don't Know of Anything That Works Like 303 Does!!!
November 12, 2012
It was a real treat for me to buy this for myself. I've known about this product for several years and have never been disappointed. I tell EVERYONE I meet - OK maybe only most of the people I meet - about this fan-tast-ic product.
ProsWhat DON'T I like about this product? No really - this is a truly fantastic product. I do have one problem with it though...
ConsWell...it is kind of pricey - I bought a 32 oz bottle for $20 before tax and shipping - I let a friend use it on his RV tires and now the bottle is almost empty! I was planning on buying a gallon but at 50 buck or so that will have to wait awhile.

October 12, 2012
Use it on everything, but mostly buy it for the interior of my vehicles. It leaves a shine on vinyl, but not much of one, which I like. But most of all, it really does protect. The hot south Texas sun is brutal on upholstery and it is very obvious, over time, that this product keeps it in good condition. I don't buy things that don't work. I have always used 303, and will continue to do so.
ProsDoes what it is advertised to do, and does it extremely well.

I originally used this product on the black plastic trim all around the outside of by Dodge Grand Caravan and the results were fantastic in that it brought back the original deep black appearance. Now, I have used 303 Protectant on my fiberglass boat aand vinyl seat covers and cannot believe haw it has completely stopped the growth of mold that would always pop up a few weeks after cleaning. A really great product!

I use 303 on my 2000 Sebring's rag top. When I first apply 303 to the top it brings the shine back to a new look. My cars top is original and 303 helps keep it looking new. I also use it on the interior and all rubber parts. Living in the desert 303 is a must.
