Paintwork like sandpaper, which product?

[Easty-5]

I returned home last week from after working away for 2 months. My car was pretty dirty so I gave it a quick wash, however, both front doors, side skirts and front wings are like sandpaper! The dirt is welded to the paint. I spent a good 6 hours today with a claybar and made a good improvement in the drivers side, although still not perfect. I think I need something a bit more aggressive than a claybar for the passenger side. I can scrape the dirt off with my finger nails, so it will come off. Just not very well with a clay bar. What other products can I try? I want to get the paint as smooth as possible before getting the DA and cutting compounds out and trying to freshen up the paintwork.

Could try a clay mitt? They're much easier/quicker to use than clay bars - http://www.halfords.com/motoring/cleaning-products...

That is exactly what I bought and used. Worked an absolute treat, paintwork is now like glass. I tried some intense tar remover first and it done nothing. Went with the clay mitt and it took sorted it out. Wasn't easy mind you and used a whole bottle of Autoglym Rapid detailer. Took 13 hours all in to do.
