I have a Kahr E9 that has just been Duracoated. Looks great! The only problem is, they painted over the sights. They weren't anything fancy. Just a white verticle line on the rear sight, and a white dot on the front. How do I fix this? Is there a special paint I need to use? Is there a trick to applying it? Should I send it back to the guy who Duracoated it? (Shipping the thing cost me a fortune!)
