2012 Acura MDX - Touch up Paint (Black)
 

I have a deep scratch about 3-4"s long, but very thin (had a ping pong table on the roof, one of the legs caught the car when taking it off)

What is the best touch up paint to use, and process you would recommend? The scratch occurred a while ago and we never treated it.

Langka blob eliminator if you can catch the scratch with your fingernail! You can buy touchup online and use a toothpick to apply the paint into the scratch. Capillary action will draw it into the scratch. dry and use blob eliminator to finish up the repair!

If you can't catch it with your finger, a OTC polish should get it out easily. You can try Meguiars M205!
