I have it in a little spray bottle. I do it every few months to get rid of the little specs from the car.
You need a DA really to apply 105 and 205 on the appropriate pads (I have a DAS-6 with chemical guy pads). I'm talking rotary polishing for those not in the know, this is not hand applied as you won't get the cut to remove swirls.

This isn't a 5 minute thing, its very intensive work for the paint and if you don't know what you're doing you can break through the lacquer and into the base coat. I do it over 2 days as i let the paintwork fully dry before i use any polish. have a look on youtube, there are LOADS of vids :)
