try a clay bar, it that doesn't do it, get some acetone. it will take the wax off but wont damage the clear

 

Clay bar

 

i tried a claybar the meguiers clay kit didnt seem to do a whole lot? how long does it take to do? like a hour for a small 12 inch section?

 

I wouldn't expect a consumer clay to remove overspray like that -- it's more for spray that has been carried in the air and not sprayed directly.

You might an "aggressive" clay from a detail house, or Meguiar's also sells one in their professional Mirror Glaze brand -- it's in a small black jar and is a red clay, and runs about 30 bucks. You will have to follow with some polishing.

Based on my limited experience with rattle can oversprays, and "etching primer" doesn't sound too friendly, you're likely going to have to polish with a rotary -- thus, I'd take it to a pro who you trust and knows what they're doing.
