Great seal for boat storage
Why did you pick this product vs others?:Ads looked promisingEase 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

Perfect
Perfect exactly what I needed and as described. Bought for my boat and is just like what was on it from the factory.

Fits Well Enough
The 3\16 edge is wide enough, but only half as deep as stock for My application. Installed in a 1976 GMC C25 Suburban with no need for adhesive. 25 feet was JUST enough for 2 of the 4 doors. Has stayed in place and seals out the rain/melting snow. Minus one star for the high price, but there aren't many options to choose from for what I needed...

Quality product.
High quality. Worked great on my truck bed cover. Old gasket was glued in and fell off. This fit well and seals nicely.

Pay attention to the channel size you need
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 It had originally been replaced by another vendor who worked on the car, but the trim kept coming loose.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.

The "tang" to hold it in place is.... well.... bad
Super disappointment. This works great.... if you take the time with a razor blade to remove or reduce the "tang" which is supposed to hold it in place. In reality what happens is this inside lip which is supposed to hold it in place forces the exterior side of the trim piece out way way beyond and at an angle which is unacceptable. Love the idea of what this "trim with a gasket" was designed to do but it was not thought through. Razor blade it smooth and a dab of super glue for install and this works super awesome. I'd give it a 5star if it wasn't for this extra tab.... but extremely time consuming for the price to have to modify.
