Product Review: 303 Protectant Makes A Great RV Wash Too

303 Aerospace Protectant Offers Excellent RV Wash & Seal

For those RV owners already using 303 Protectant to extend the life of the various fittings and surfaces on your RV, there is also a great RV wash product available by the same manufacturer. Not only does it foam well, but it also leaves a high-gloss UV-protected finish. While many products claim to do this, they don’t have the same pedigree as 303 Protectant, which is frequently discussed on popular RV forums. What surprised me the most was how clean the finish was after washing. No, it was not completely spot-free, but it was remarkably better than what I have used in the past. 

Accidental Purchase With Great Results

I actually ended up with the 303 Protectant RV Wash & Seal by accident. I was looking to replenish my jug of 303 Aerospace Protectant and inadvertently added the 303 RV Wash to my Amazon cart instead. Upon checking out I noticed my error, not realizing that 303 even made such a product. I added my standard 303 Protectant to the cart and had both shipped to my home.

Having owned an RV for several years, my typical washing process was to first wash the RV down with a quality RV soap suitable for gel-coat. This always left me with water spots. Bear in mind that I do not have one of those great deionized spot-free water systems to rinse the RV…yet. I would then wipe down the entire RV by hand with Protect All. The result was a clean, shiny, and well-protected RV. As you can imagine, with a big Class A motorhome, this process took quite a while.

A Clean Wash in Less Time With 303 Protectant RV Wash & Seal

With the new goods in hand, I decided that when the weather was suitable, I would put the 303 Protectant RV Wash & Seal to the test. On a mild Texas morning, I went through the same washing procedure as normal, but with no wipe down. While certainly not 100% spot-free, the clarity of the finish was remarkable. As someone who is very particular when it comes to the way things should look, I was anticipating the full wipe-down process. I found that from many angles, the RV looked good enough to leave as-is. I suspect if I had one of those deionizers, it would have been a perfect finish.


The results of my 303 Protectant test were quite surprising. The RV looked fantastic, and I was secure in trusting the 303 name to protect my RV from UV rays. In another few weeks it will be time to scrub the roof again and treat all the incidentals (A/C shrouds, vents, etc.) with 303 Aerospace, then wash the rest of the RV again. I anticipate that I won’t need to do a wipe down, but it will be fun to see if the results are similar. 303 recommends wiping down any vinyl or plastic surfaces with their 303 Aerospace Protectant after washing with RV Wash & Seal. I will typically treat things like the marker lights, headlights, and taillights…anything plastic, with 303 Aerospace Protectant after the RV dries. I keep my tires covered, but when uncovered I wash and treat those as well.

  1. Wow! I need this. I harvest rain water living in the southwest so no water spotting occurs. Only takes about 5 gallons on a 33 ft class a

  2. Hello Patrick,

    I headed the reviews of this product online and I ready make it a habit to read the negative ones. It sound like this strong stuff and need to wear gloves using it. One of the biggest complaint was that there are no ingredients on the label. I don’t think I’ll be using it.

  3. I use 303 protectant on our Palomino RL 181 and will be getting the RV wash for sure. So far my 4 year old camper is not showing any signs of fade or discoloration from the sun.

  4. I’ve been using 303 Touchless Sealant on my motor home and classic cars for 3 years, so easy, great protection and shine! Makes bugs just wash away on the front end, I may have to try the wash!
