I have a week off in a couple of weeks and I'm planning on sorting out all the stone chips on the front of my Bella. And a scrape on the tailgate ironing board (All accrued under the ownership of the previous driver

)
I know the paint code (Silver 612/A according to the sticker on the boot) but dunno where to get the paint from (since Halfords don't stock Alfa colours)
Anyone know where I can get an aerosol from that will deliver it at reasonably short notice?
Also, what colour primer should I use? Touch ups on my last silver car needed a grey primer, so I assume this would be the same?
thanks for your help guys
