Extra sticky. Used on strip LED. Clean surface 1st with alcohol. No problems whatsoever.

I love how sturdy this 3M VHB heavy-duty tape is when it’s fresh, it holds flawlessly and blends right in, making installations effortless and clean. But after about four months, the adhesion noticeably weakened, and some items started coming loose. Now I know it needs surface prep and curing time to perform best, but buyers should be aware it’s not a permanent, forever solution especially in warm or exposed areas. I still rate it 4 stars because of the excellent initial performance and versatility but you’ll want to treat it like a semi-permanent adhesive, not a lifetime guarantee.

This stuff worked to hold the back seat of my car plastic that kept falling down from weak stuff used stock

I've used lots of double-sided tapes over the years; this is, hands down, the best I've found for applications that don't require paper-thin tape (i.e don't buy this for internal repairs of your phone or laptop.) This is the only tape I've found that can keep a phone mount stuck to my black dashboard through a Southern California summer; every other brand I've tried goes soft and gummy in the heat. I've used it to stick locators onto the backs of all the TV/video remotes in the house; one of them got run over (it's a long story) and the remote was crushed - but the tape held. If you ever need to separate things you've taped together, it's surprisingly easy and clean; use a razor blade under an edge to get started, and then twist - DO NOT PULL! Cleans off with no residue. I have no idea what witchcraft 3M performed to make this stuff, but it's amazing. If I have one issue, it's that the backing is hard to pull off; it can be a little frustrating to get started, but once it's started it peels off cleanly. Once your two surfaces (e.g. remote and locator) are stuck together, press them together for 30 seconds or so; it seems to increase the strength of the bond significantly.

This is good for under the counter lighting systems and it does not loose grip over time, stays in place.
