Good quality product
Great product, works as advertised, used to seal the front glass on my excavator, much cheaper than purchasing from an equipment dealer. Very good quality.

Great seal for boat storage
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
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 It had originally been replaced by another vendor who worked on the car, but the trim kept coming loose.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.

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...

Works for North River boats
My husband used this to seal his back entry door on his North River boat. The factory seal on the boat started to flatten out an let water thru. This did the trick.

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.

Struggling to stay dry
I was struggling to keep a storage area on an RV dry. The RV was pretty new and just started leaking in one storage area. This was exactly as described, very easy to install and worked perfectly. The old seal looked good, but this one stopped the leak.

After repeat attempts I was sent the wrong item. Heard good things about Trim Lok and was hoping to use it. Needed it sooner than later. Had to go with a different product.
