Can I use RV fiberglass wax for my car?

I was wondering what is the absolute best RV wax for fiberglass that provides the best protection, is long lasting and suitable for most of RV. Besides an class C motorhome for camping trips across the country with my family, I also own a 2016 BMW 5 Series. Normally, we use Meguiar’s product for waxing our RV after researching and reading some good piece of info about it on the internet. It worked great with my RV to slow down the oxidation and make ultraviolet shield. But I've not used it for my BMW. Is this good for car? What is the wax that you usually use for your car? Any suggestion?

There are a number of different Meguiar’s Marine waxes. Most people probably use their Flagship Premium Marine Wax but it does include a mild abrasive. If you need a little light polishing for you car it should be fine. I have used it for very light scratches on my car.

Then there is Meguiar’s pure wax (not really pure but thats quibbling) , and being a "pure" wax, it should be fine for cars also, just maybe more expensive than need be.

On my Fiberglass RV, when no further cleaning or polishing is needed and I want a pure wax, I use 3M Marine Ultra Performance Paste Wax. My car does not get treated so well.

I've always felt that the difference between Car Wax, RV Wax and Marine Wax was that they were "specially formulated"for the specific purpose of getting more of your money by selling you another can of wax when you already have a product that would do the job very well.

I tended to think that way, too. However, after using regular Turtle paste wax for several seasons and switching to Meguiar's a year ago, I'm now convinced it's worth the extra cost. It is both longer lasting and easier to buff out.

I bought my Scamp used, and I don't think the first owner ever waxed it, so the original gelcoat shine was long gone. No matter how hard and long I buffed, the paste wax always came out blotchy. The Turtle wax was gone on top after only about 3-4 months, while the Meguiar's still beads up after 6 months in our high altitude AZ sun. As they say, YMMV...

I still use Turtle paste wax on the cars, but like Gordon, I'm not as picky and prefer to save the pricier marine wax for the Scamp. Automotive paste wax seems to last much longer on the cars' clear coat finish. Once a year for the cars, twice for the Scamp.

Ever since I've owned my Scamp from 2010, I've used "Protect-All". I let it cover the rubber window seals, cords, everything AND I use it on my vehicles. Meguiars is about $.47 an ounce and buying this PA in the gallon size is about $.32. I've had good luck with it. But I've also caught it on sale AND when Camping World wants to "get you back" and offers a instore discount etc. So that's a good time to buy in "quantity" which always saves. Protect All has good reviews as well.

wax on cars

I have 2 cadillacs both old one a 2002 one a 2005 the 2005 has 69k on it I have never waxed them.

with our new finishes I don't think waxing needed but if you want go for it! as jon did I bought our 13f scamper used it did have a high dollar finish on it but I don't think my back will handle much so if it get an occasional wash that will be it.

as its a 95 the old girl is showing her age a little but aren't we all. one thing just think of the money all those companies are making off the car waxing business?

I am a bit disappointed that no one has mentioned floor wax. Zep Wetlook, available at Home Depot. $30 Cdn for 3.78 liters of the stuff. Way more then you will need. It is designed to stand up to UV and more ware and tear then you fibreglass trailer should be subject to. Best of all, after three or four years, you can take it off with the engine wash setting at the wand wash. Then put it back on. Take a look at this thread:

The hardest part is getting the trailer real clean, before applying it.

Using Meguiar's, I was very impressed by the ability to remove oxidation and it makes for a nice shine. i bought this product after reading a detailed reviews about best RV wax for fiberglass and then I bought a can of Meguiar’s M5032 Marine on Amazon. I applied by hand but removed by both buffer wheel and by hand. Once dry, it removed easily. In regards to scratches, it may deal with very light scratches but I did not see much improvement over some slight scratches that I had.

I applied it in direct sunlight just to see how it worked and it still came off easily. I used this on both the metal and fiberglass portions of my rig and it did great. It was not smooth metal so it took a bit more elbow grease to remove it. It has since rained and it does a great job repelling water, keeping my rig looking sharp. I can't comment on longevity but if it's like any other Mequiar product, I expect it to do well. I use nothing but Mequiar's and this product did not let me down. Again, the removal of oxidation and other surface grime was fantastic with this cleaner/wax!! Extremely impressed and I recommend this to all of my RV friends.

Yeah, maybe at my first thought I considered all vehicles are the same so the wax for RV would work for other vehicle: cars or boats.

Good point, though the real question seemed to be whether he can use it on his 2016 BMW 5-series. Not advisable...

I'm thinking you're probably right for brand new gelcoat. As gelcoat degrades with exposure to weather and UV radiation, it becomes rougher and somewhat porous, unlike modern vehicle clearcoat finishes, so it doesn't take wax evenly. The fiberglass-specific products seem to do a better job of overcoming that. As David says, high gloss floor wax has also been used effectively on older gelcoat. It lasts longer and gives a higher gloss, more like new gelcoat, but it has to be stripped before reapplication.

I should mention that I started with the full Meguiar's 3-step restoration process- oxidation remover, conditioner, and wax. For reapplication, if it still beads water, I go straight to the wax, but if the wax is completely gone, I back up to the conditioner step.
