Disappointed. have the tfx-pro on my cz-75 - TruGlo Brite-Site TFX Pro Sight Set For CZ 75 Series

Disappointed. Have the TFX-Pro on my CZ-75. Great at night and during the day, the sights pop right out for easy sight picture, BUT the red ring will rub right off during cleaning. I only use hoppes # 9 cleaner like everyone else. Cleaned the front sight with a Q-Tip and the red ring came right off. I did email Truglo and ask them what paint should I use, to reinstall the red ring. There response was they could not tell me what type of paint to use or how they would install the missing / faded red ring.
