I purchased Sugru years ago to form a small cover on the edge of my MacBook Pro's palm rest because it was uncomfortably sharp. Basically a thin line of Sugru from edge to edge.
It worked well, and it's still there and functioning 5 years later.
When the two tiny packets arrived I thought it was quite expensive for what it was! I only ever used one packet, the other stayed in the fridge door where I just found it and it is rock hard. So I guess my next purchase would be for this Blu Tack.
- Balero 8y agoBlutak would not work for this. If you have it in contact with body heat too long it gets ropey. It would constantly stick to your hands on contact. I think OP was commenting that they're completely different things, with different purposes and uses. Blutack is great for sticking a poster to a wall, because its easy to put up and take off, and can be useable again. It is not for something to be permanent and used.
- oldcynic 8y agoYup. They're solving entirely different problems. Sugru would be great but for the really short expiry as it's just the sort of thing I'd keep by indefinitely for an unplanned repair along with glue, tape and epoxy putty.
- robotmlg 8y agoBlu-Tack doesn't harden, it stays sticky. It's used to attach posters to the wall and stuff like that. I wouldn't want to use it on the edge of a MacBook, it would just gather dust and grime, and would easily fall off.
- cstross 8y agoIf stuck to posters or wallpaper it also leaks oil/plasticizer over time (months to years) which is absorbed by the paper and causes staining. I discovered this the hard way in my late teens/early 20s. Solution is to apply some Sellotape (Scotch tape) to the back of the poster first, then put the Blu-Tack on the plastic tape, which blocks the solvent. And avoid using it on wallpaper (emulsion or gloss paint is fine). Better still, use poster holders and a picture hook, or go the whole hog and frame your artwork properly. Sugru ... air-cures: it doesn't have the solvent-leaching problem, but if you used it on a poster the only way to get the poster down would involve a chisel or sandpaper. Blu-Tak is for temporary attachments; Sugru is intended to be permanent.
- weavie 8y agoIt will also stain the wall and sometimes pull the paint off if left on for long enough.
- hinkley 8y agoI think they fixed it since but I recall my last MBP had a wicked sharp edge on it. I used a different trick though, the same one you do when you use tin snips. You can burnish a sharp edge on metal objects. I took a round screwdriver handle and rubbed it on the edge at a 45° angle and it was gone.
- hinkley 8y agoOops, I meant screwdriver shaft not handle. That just tears up your screwdriver!
- jonhendry18 8y agoThe sugru that's been in the fridge might be rock hard just because it's cold. If it warms up and is still hard, then it's no good.
