Ive use skint before. I guess same material 3M decals. Yup I put it on my HP notebook no residue left behind. But peeling it off is about tricky as it gets. At one point I thought I rip off the top panel off the LCD.

All I had to do was stick my fingernail under a corner and start peeling, using my other hand to keep the lid shut. At no point did I feel afraid I'd rip the computer open.

Could it be that your decal wasn't actually using 3M adhesive, but rather some off-brand?
 
What. No.

no need for the sarcasm some people really don't know that other colours are not actually carbon fibre (some people can't even tell the difference between the real thing and a dodgy fake) and I am aware that this is a vinyl sticker but I still think it's worth knowing

Skinit is not a off-brand. Actually they started this skin thing
