Cheers for the advice guys. Gonna see if I can find some time today to start filing it into shape.

The clears finally cured/hardened about 2 days ago, so I sanded it down with some 600, 1200 and 2000 grit sandpaper soaked in soapy water. It levelled out nicely, but I couldn't seem to buff it up to that nice glass-like finish I was hoping for. It was almost a satin-matte finish, which was pretty cool by itself, but not what I wanted this time. So I hopped in the car, drove down to Supercheap and bought a bottle of Meguiar's Ultimate Compound. I was really hesitant about buying it, as I'm quite sceptical about the difference between a $10 bottle of Turtle wax scratch remover and a $32 bottle of Meguiar's stuff. I saw it as a bit of a gamble, knowing that it would either be the best $32 I've spent, or the worst...
So I got it home and started rubbing it in and bloody hell! I now understand why people rave about this stuff! You can see in the picture below the reflection of my hand, which I'm still astounded by!

So, so far, I am extremely happy with my redo decision. Now just to take the hardware off the headstock, touch it in and add a few gloss coats. In the meantime, I'll have to file out the hole for the P90 and start re-wiring the electronics. Should be pretty straightforward, and I'm switching out the pots and caps for some that I have from a Squier tele that I upgraded a while back. They should be slightly better quality that what is currently in it, so hopefully that will help with the sound also!
