Just be aware that the Tru-Oil may yellow a bit. It can have a tendency to shift blues to greens. Not a problem if you like the greens!
I think it's a good idea to avoid *actual* steel wool, which can leave metal filings. That can cause two common problems, only one of which applies in your case. The one that does not apply is that they can rust when exposed to water based finishes. The one that does apply is that they are can eventually migrate to the pickups. I think most folks either use conventional sandpaper or sanding pads (eg like the 3M type)
That's great! If it was easy to get you may want to post the brand. Always good to know the locally available products that work well. WA is the postal code of my home state of Washington in the US. I don't think there's a Bunbury there, so I am guessing you are in Western Australia... In any case your alu tape will be local somewhere! ;-)
