I know this may sound like stupid question, but did anybody try to remove sound deadening material from a computer case? Thing is I applied Be Quiet material on the side panels of my Lian Li case that is made of multiple layers of bitumen, foam and fabric. The glue holding the layers together lost its stickiness from the heat and the layers have separated leaving only the layer of sticky bitumen on the side panels. Now here comes the hard part - is there a way of removing bitumen from aluminum without damaging it? I tried heating it with a hairdrier and it did come off a bit but I almost tore the skin on my fingertips trying to pry it off. I don't have a heat gun, but if it is the only way then I'm fully prepared to get one. I understand that whatever the method I'll have to clean the messy residue of glue and tar with some strong solvent - good thing anodized aluminum does not get damaged by it.
