I use Langka paint chip repair (and OEM paint).
It's a do-it-yourselfer kit that is perfect if you don't have a whole lot of time or $$ to fix chips. With a little practice - you can make some light chips/scuffs disappear (pending paint color). Deeper ones aren't as easy.
Metallic paint colors are harder than plain paint colors.
I've used this on our corvette and made certain areas totally disappear. I've gone over previous owners chip repairs and made them look 80% better. On the truck, I've repaired a deep chip on the hood - but you can still find it, it's not that bad. The metallic paint makes is harder to blend in. Another repair on my door is impossible to find.
The neat part about this Langka stuff.... you can repair the chip and if you're not happy with the results, you can literally clean off the original repair and start all over again. Practice and fine tuning the technique makes a big difference.
