sealed the drafts in my windows right up!
This product works just fine for what I needed it for- sealing up a draft in a window. It was perfect, easy to use, stuck well to the materials my window is comprised of, and did the job, which is most important. No more cold air seeping into my room during wind and snow storms! Im very happy with this purchase. You might have to purchase 2 if you are sealing up larger windows, but the one pack worked well for the two medium sized windows that I have in my room. Highly reccomended!

Great performance
AutoScan is my favorite, it checks over ten systems (ECU, ABS, TCM, etc.). The ABS system will exactly tell you which wheel has problem, the left front or right rear. When I replaced the heater motor, I didn't open the lid, which put the fresh air damper in a difficult position. This tool has taught me this. It's great to have so many scanned things. Still learning, very good.

Gap Sealer
I watched a youtube channel about these for "soundproofing". Very inexpensive and makes a world of a difference in sound bleeding in and out of the room. Very sticky, but easy to take off and adjust it. Just make sure you clean the surface before putting it on.

no more light
No more light coming through the door when it is closed. Used to be I could see light between the door and door frame when the door was closed before installing this foam tape. I really hope it stops cold drafts this coming winter. This stuff sticks good! I messed up and thought I could peel it back A few inches, no way it sticks too good to painted wood frame.

Average performance, easy to apply, good for maybe one season.
Before switching to silicone weather stripping ($20 from Trademark Soundproofing) which dampens noise, light and cold, I bought four of these packs in December 2020 (for $2) and applied it around my door frame to keep out the cold, and it performed okay. It was easy to apply but difficult to remove without tearing and leaving behind residue, and it kept out some cold for a few months but also made the door much more difficult to close due to its shape. Ultimately I would recommend this foam if absolutely nothing else is available or if cleaning torn pieces and residue is little problem, otherwise soundproofing products will likely outperform this weather seal and last far longer, justifying the increased price. Case in point, before switching to a more solid door my silicone weather stripping lasted about three years and blocked out light, cold, drafts, noise, and even made the door close more quietly due to its shape. In this case I certainly got what I paid for. Nonetheless for being a temporary solution sold at a rock-bottom price, the “Frost King R338H Self-Stick Rubber Foam Weatherseal, 3/8"W, 3/16"T, Black|Blacks” gets a serviceable 3/5 stars!

Very Good Product
I bought this to help my windows seal properly on my car to prevent air from being heard inside my car. The sponge Rubber Foam Tape worked very well to prevent wind noise inside my car. The price was affordable, and delivery was fast with Amazon Prime.
