Style chooser

Hi guys,
My car paintwork looks fine, but when i touch it, it feels a bit rough. I am probably being a bit anal, but is there some way to remove the roughness?? I think its caused by the fact that I park in under the hot sun for long periods (especially during work, company doesn't provide covered car park, plan to picket soon :p). I tried polishing it, but it doesn't really help. I was thinking of claying it and also getting a better car wash, the one i am using is the el-cheapo type. Will...
