I have 3 BB marks on my passenger door from goofy kids in the neighborhood one day shooting up cars. Where can I get the touchup paint - my H3 is boulder grey. I went to autozones and no one seems to have it.

 

No Auto zone or other retailers are going to have that factory paint.
I have the same problems of small dings that needed touch up.
This company in New Orleans is one of the best I have worked with.
They are accurate and fast

If you have a 07 Boulder Gray Metallic vehicle, check your glove compartment for the code. It should be U926L.
The first letter U or WA are irrelevant.
Many web sites call this color Silver Birch Metallic. The code is the main and only number you need when ordering

I also ordered the 12 oz spray of this color and a can of the clear coat. I painted my wind/bug deflector to match the body color. It is a spot on match
You won't be disappointed
good luck
