Help!!! How you remove dried cement splatter on paint?

I must have driven next to a cement trunk or near some wet cement. Now I've got a dried up cement splatter about the size of a dime on my trunk. It's really hard and on the paint pretty good. How do I get this off without destroying my paint. Please help guys!!!

I picked this up from another website somewhere in case I encountered concrete or very hard, calcified garage parking drips. I've never had the occasion to use it so I don't really know how effective it is but thought I'd share it if it does work:

HOW TO REMOVE CONCRETE SPOTS (garage parking) OR SEVERE WATER SPOTS:

Concrete Spots:
Calcified water spots on paint and glass, water and concrete spots are pretty much the same chemically - calcium carbonate, with the concrete being cross-linked with water

Methodology
•Apply 1:1 ratio water with distilled White Vinegar solution, and using a spray bottle, spray that mixture on the spots and let them "soak." Then rinse with water and repeat as necessary.
•If the ambient temperature water/vinegar mix does not work, warm (100-120 degrees) 100% distilled White Vinegar, saturate a clean kitchen sponge with pure vinegar and hold the sponge over the concrete spots for a few minutes.

•If the above do not remove them try equal parts distilled water, isopropyl alcohol and distilled white vinegar. The acid in the vinegar will help etch and dissolve the concrete.
•Rinse the area thoroughly with water after the vinegar and then reapply wax or sealant to that area.

I used wd40 and let it soaked and repeated until all was removed
I used a hose to rinse and waxed it when I was done
