What are the drawbacks of car sill plates?

Aftermarket sill plates are prone to friction with the car door. Since sill plates are attached with strong adhesive, they may loosen or fall off over time. Here are some related issues: Paint scratches: For SUV models, if there are children or elderly family members frequently stepping on the car sill when getting in and out, prolonged friction can cause paint scratches. Installing sill plates can effectively prevent this. Detachment: Frequent detachment of sill plates is often due to improper installation. Before installation, the sill area must be thoroughly cleaned and kept dry. After application, pressure should be applied to ensure full adhesive contact. Using a hairdryer to heat the adhesive can also help achieve complete bonding.

The biggest issue with door sill protectors is the residual damage after installation. When I changed cars last time and removed the old sill protectors, I found stubborn adhesive marks underneath that wouldn't come off even with adhesive remover. Those shiny stainless steel strips get dirty easily too - during rainy days, all the mud and sand from shoe soles get trapped in the grooves, requiring a toothbrush to clean. Over time, I also noticed the edges started lifting slightly, often catching my pants when closing the door. What's more annoying is that during car washes, water seeps into the adhesive layer and gradually corrodes the paint. Now I think going without them is actually more convenient - just being careful when stepping on the door sill is enough. Even if it gets scratched, repainting is simpler than dealing with those adhesive marks.

Threshold strips can actually be quite troublesome after prolonged use. The anti-slip particle type I installed on my car became even more slippery after two years when the particles wore down, nearly causing me to slip on rainy days. Material quality is also noteworthy - a friend bought a cheap one that rusted within six months, leaving yellow stains on the paintwork from rust runoff. Installation alignment is another issue; I once discovered at a repair shop that the mechanic didn't position it properly, causing the door to always catch on the frame when closing. Now I have to specially clean the gaps around the threshold strip during every car wash, otherwise accumulated dust easily leads to mold growth. While they do protect against scratches, maintaining them proves more troublesome than simply cleaning the car's paint directly.

The most concerning issue with scuff plates is the safety hazards. Last time, my family member slipped on a wet scuff plate while getting out of the car, hitting their elbow against the door frame and leaving a large bruise. Some low-quality products have sharp edges, and my child once got their calf scratched. There's also the problem of nighttime glare—after installing chrome strips, the reflection when opening the car door at night is blinding. What's even more annoying is that in winter, the rubber strips harden, and I once tripped when my shoe heel got stuck in the gap. I genuinely recommend not installing them on cars that already come with factory-applied anti-scratch coatings—it's just unnecessary.
