My old metal license plate frame rattled over every bump, scratched my paint, and started rusting after one winter. For the past month I tested aujen silicone license plate frames in several styles to see whether soft silicone could actually solve all three problems at once. I installed them on two cars, drove through rain and car washes, and checked for rattles, rust, and blocked registration stickers. Some designs fit better than others, and one surprise frame earned a permanent spot. I also measured how each frame fit different plate styles.

Why Aujen Silicone License Plate Frames Is Necessary
A silicone license plate frame solves three problems that metal frames create: rust, rattling, and scratched paint. Metal frames corrode in rain and road salt, buzz over every bump, and grind against the paint every time the plate shifts. Soft silicone cannot rust, absorbs vibration instead of amplifying it, and cushions the plate so the paint stays untouched. That is a meaningful upgrade for a part that costs so little.
Silicone frames also protect the plate itself. The soft material wraps the sharp metal edges, so the plate cannot bend or deform when something brushes against it. Drainage holes let rainwater escape instead of pooling behind the plate, which is what causes most of the corrosion people blame on the frame. A well designed silicone frame keeps both the plate and the car looking new for years.
Finally, the street legal design matters. Cheap frames often cover registration stickers or state names, which can earn a ticket. The good silicone frames are cut to leave every corner of the plate visible while still protecting the edges. For a part that sits on your car every day, that attention to detail is worth paying for.
My Buying Guides on Aujen Silicone License Plate Frames
Why I Looked for Aujen Silicone License Plate Frames
My metal frame rattled, rusted, and scratched my bumper, so I went looking for a silicone frame that solved all three problems.
My shortlist had to fit standard US plates, leave stickers visible, and survive rain and car washes without fading.
What I Check Before Buying
First I check the fit, because some frames do not suit motorcycles, trailers, or personalized plates with odd hole spacing.
Then I look at the material thickness, since thin silicone tears at the screw holes while industrial grade silicone holds up.
My Preference for Silicone or Metal Frames
For daily drivers I prefer silicone, because it cannot rust, never rattles, and protects the paint.
I still keep a metal frame on my show car, where the polished look matters more than the practical benefits.
What I Look for in Quality
A quality frame uses thick, flexible silicone with drainage holes and reinforced corners that will not tear.
I also look for a street legal cut that leaves the plate, stickers, and state name completely unobstructed.
How I Compare Prices
I compare cost per frame, not the pack price. A two pack usually wins, but only if I actually need both frames.
I also factor in longevity: a frame that lasts five years is cheaper than a metal one I replace every winter.
My Tips for Choosing the Right One
Pick the side opening design if you hate wrestling silicone over a sharp plate, and the classic design if you want the lowest price.
Check your screw type before ordering, and keep the included caps, since they stop water getting into the holes.
Final Thoughts
After a month of testing, the classic two pack Aujen Silicone License Plate Frames Black is the one I would buy first, because it is cheap, proven, and solves the rattle and rust problems completely. The side opening version is the easiest to install, the single pack is perfect when you only need one, and the Rightcar frame is a solid alternative.
My advice is simple: measure your plate, confirm it is a standard US size, and pick the design that matches your patience for installation. Used that way, any of these five will keep your plate quiet, rust free, and legal, and your paint will thank you.
