Diamond Shield – No More Cracking And Mold

The Diamond Shield badge

Diamond Shield, or any clear front end protection film, can be a blessing or a curse for motorhome owners. And when you visit RV forums on the internet, you will see both extremes. Some love their Diamond Shield installation. On the other hand, some hate it. So why the extreme opposite opinions?

Diamond Shield – what does it do?

The purpose of a clear front end bra for an RV is mainly to help protect against rock chip damage. But it can also be helpful with bug splatter and road grime. There are other ways of providing RV front end protection, like a vinyl RV bra or a plastic RV shield. But the big advantages of clear protection film is its invisibility and ease of use.

In fact, the average person would usually not even know that Diamond Shield is applied to a motorhome. You have to get up close to even see the outline of the shield. And there is nothing to remove and clean like other forms of RV front end protection. Because the front end is clear it also doesn’t interfere with the paint scheme of the RV either. So why do so many RVers hate Diamond Shield, when it has so many clear advantages?

Clear front end protection film problems

The real problem with clear front end protection film is that it is easily affected by the Sun’s UV rays. Ultraviolet rays over time can bake the film, causing it to crack, yellow, and fade. Worse yet, when the shield begins to deteriorate, moisture can begin to penetrate underneath. When it does, mold can easily begin to grow. And once that happens, there is practically no way to stop the mold from spreading.

So the once beautiful Diamond Shield installation can become cracked and filled with mold. When it does, the RV’s front end looks horrible. And this is why so many Diamond Shield owners are dissatisfied, to say the least.
So is there any way to prevent the deterioration of Diamond Shield? Yes, there is. The real problem is that in most of these cases, the Diamond Shield RV owners have not maintained the shield. And yes, some maintenance is required to make sure that Diamond Shield lasts a long time. It is not a product that can be installed and forgotten about.

But clear front end protection film does not require a lot of maintenance. In fact, it shouldn’t take more than about 5 – 10 minutes to do, with little effort. And anyone can do it, with products that are inexpensive and readily available. 

RV front end shields – how to maintain them

Remember that the enemy of an RV rock shield is the Sun’s ultraviolet rays. So the product that the Diamond Shield main office recommends most to maintain the shield is 303 Aerospace Protectant. This product is a high-quality UV inhibitor, and is highly reviewed and recommended. Just spray it on the shield and wipe the excess off with a high-quality microfiber towel. It is just that easy.

Some RV owners take their shield maintenance a step further though. They also use a polymer sealant on the shield before applying 303 Aerospace Protectant. This kind of synthetic wax sets up a moisture barrier that further protects the shield from mold. In fact, you can apply a couple of layers of the polymer sealant if you wish. Then layer the 303 Aerospace Protectant on top of the sealant. And all of this protection can be applied to the RV bug shield easily with microfiber towels in just minutes. 

There are plenty of good polymer sealant products for the auto and RV market. Almost any of them would work well. The one I like to use most often lasts longer than most. But if you have a favorite of your own, I’m sure it will work just fine.

I often use Optimum Car Wax as a polymer sealant. Find out more about it by clicking the photo below

How often should you maintain your Diamond Shield?

How often should this maintenance be applied to Diamond Shield? A good rule of thumb is to apply it once a month. But if your RV spends a lot of time in high humidity areas, you may want to do it more often. Perhaps even every couple of weeks or so, just to be sure the protection is adequate for the area. This is especially true in lower Texas and Florida, where humidity can be extremely high.

Of course, you don’t have to apply the polymer sealant too. Just 303 Aerospace Protectant alone will do a great job. But if you have the extra time, adding synthetic wax to the protection regime can be beneficial too. The key to RV shield maintenance with a diamond shield protective polish is having a regular schedule for it. Then follow that schedule consistently.

If you have Diamond Shield, or any other RV protection film, you can keep it looking great. And it isn’t hard to do. Make sure that your regular RV inspection also includes inspecting your rock shield. Then follow the maintenance guidelines in this article to get good results . If you do, your Diamond Shield should last a long time and look great while it does!

    What do use on the Diamond Shield to remove bugs?

    1. Hi Cheri, I recommend a product called “Bugs N All” sold on Amazon. Here is the link – https://amzn.to/36UOr7f But after getting the bugs off be sure to reapply “303 Aerospace Protectant” ( https://amzn.to/2Lsyydz )for your shield’s UV protection from the sun. If you apply that product every month to the shield, it will last much longer.
