### ⭐⭐⭐⭐⭐ Good quality product
*by D***N on December 24, 2025*

### ⭐⭐⭐⭐⭐ Great seal for boat storage
*by J***R on July 8, 2025*

Why did you pick this product vs others?: Ads looked promising Ease of installation: This was very easy to install. Cut it a bit long and then used some marine silicone on the ends to join it together. Works great

### ⭐⭐⭐⭐⭐ Pay attention to the channel size you need
*by A***N on July 26, 2021*

I was replacing the door trim seal on my car. It had originally been replaced by another vendor who worked on the car, but the trim kept coming loose. When I finally got down to fix it, I found the channel size was nearly a quarter inch, which was too large for the metal edge it was attaching to. It took me a while to research and check specs on different size trim seals and this one appeared to be the best fit. Once I received it, I put it right into the car and it fits like a snug glove. The trim now stays in place and it looks good. Moral of the story is to measure the thickness of the metal edge it will be attached to and then get a trim seal that is slightly -smaller- to provide a good snug fit. In my case, I used a set of calipers and measured the edge at several places. The quality of the product is nice, with both a good overmolded metal channel and a thick but pliable bulb for sealing. Overall very satisfied with this.
