Overspray

As I have been restoring my car I have been stupidly using rattle cans in the garage to touch things up. I noticed the other day that there is an overspray on my new paint job. I have hit it with a light buff and it looks ok but I can still feel the roughness with my hand. What is the best way to get back to the smooth slick surface I had? I am hoping I don't have to resort back to wet sanding :(
 
You could try a clay bar with a detail spray? They also make special pads for removing overspray/ and other contaminants that can get on a painted surface.
 
Clay bar is the thing for that, but you have to be very careful to keep everything spotless clean, because any particles in the clay will scratch the paint.
 
I really think I need to so more buffing, there are still scratches I can see in the sunlight from the wet sanding. Should I just hit it with the wool pad and compound or should I do something else first?
 
Hit a small area and see if the scratches and overspray go away quick enough. Spray bomb overspray can also be removed with xylene. If the vehicle is all SPI, it should be solvent resistant enough to do without trouble, but obviously try a small inconspicuous spot first.
 
I was brave enough to crank up the RPM on the buffer to where it should be. It is slicker than snot now....

I've got some very fine clear overspray on my '37 body shell. It was more like a fog, covered everything, but you can only make it out if you rub some off. There's not really a haze, just that you can feel it. I was going to try some clay bar on it, but wondered if there is one that everyone recommends. Chemical Guys make a light, medium and heavy duty and I was considering the medium unless I get some better recommendations. I tried polishing a bit off using 3M ultra fine, and it comes off fairly easily, but would rather try a clay bar and avoid removing any clear if I can. This happened when my exhaust system failed and allowed clear coat fog to migrate outside the booth. It was only exposed about 10 minutes but enough to cover it. Thanks, Bill
 
Thanks Shine, I'll give that a shot. It will work I'm sure as the 3M ultra fine works ok, but I was thinking for door jambs and things that a clay bar would risk burning through on corners etc.
 
Clay bars must be followed by polish in nearly all cases, so if polish removes the overspray, you are ahead one step and have avoided possibly scratching the paint with an errant particle caught in the clay,
