Hi
I'm not sure I'd spray WD40 on a SGI Crimson. You might remove more
than tape gum. On typical hard surfaces, things like GooGone work well
but this might not be good on your surface either.
I'd try first using the tape method. Get a piece of the same or similar
tape. Place it in the old gum and then remove it slowly. The tape
will ofter pull up the older gum. Soemtimes, it works better if you
let it stay in contact for a hour or so.
Try to do experiments in a location that doesn't show. Any of the
typical solvents can remove the nice surface of your Crimson, leaving
a shiny metal instead.

The WD40 is on hold, as it appears I've lent out or disposed of mine.
It's impossible to know what type of tape was used, other than it was quite
wide and in place for rather a long time! When I do get hold of some WD40
tomorrow (GooGone doesn't seem to be available in the UK based on a cursory
check) I'll test it on the rear of the "wheel covers" to ensure no lasting
damage (should it prove too harsh.) I've sprayed it on and around ABS
plastics in the past without any harm, however.
As regards removing enough surface to reveal metal, that would probably take
a strong sulphuric acid - these babies were made solid, and that includes
the non-structural "skins". For each of the pieces I've removed, the
thinnest I've found is 4mm.
