Thank you for your question regarding the Delta Square Wall Elbow for Hand Shower and I am happy to assist you today.
Unfortunately, we do not manufacture touch-up paint for our accessories, nor do we have any recommendations at this time and I apologize for any inconvenience this may cause.
It may be best to look into companies that carry repair and coloring kits, similar to Multi-Tech Products to see if they may carry a touch-up paint to match the Matte Black finish.
I hope this is helpful and I am sorry I couldn't assist you further with this issue.
Please feel free to give us a call if we can help you with anything else going forward at 800-345-3358.
