Black Car, 20 Years Old - Paint Resto

[V8 Disco]

Hi, my 93 Skyline is black - it was standing for a year before I bought it and since putting it back on the road I hve been able to bring the paint back to a reasonable finish through washing and polishing with some black polish from Halfords. I have used Meguiars Scratch-X on some of the worst blemishes and even sucessfully done a couple of deep scratch fill/wetsand/compound jobs. Now it's looking better, I can see loads of really fine scratches and swirl marks in the paint that I'd like rid of.... any advice?

I might be able to borrow a polisher from a pal...... not used one before though.

It's solid - I have read some basics on using compound to polish (keep away from edges etc) and I understand that a DA polisher will be better than simple rotary ones..
