What is the ruling on wudhu with some dye or polish (paint) present on the body parts to be washed? And does one have to repeat his prayer if he noticed it after finishing his prayer? الوضوء مع وجود بعض الصبغة والبويا

Praise be to Allah, and may Allah’s peace and blessings be upon the Messenger of Allah, his family and his companions.

As to what follows:

In response to your question, we say, and with Allah Almighty lies all success:

It is compulsory for him to repeat his prayer in which the body parts to be washed in wudhu had a part of or barrier to water reaching them. This is so because the prophet (peace be upon him) saw a man with as much as a nail’s size spot on his foot which water had not reached. So the prophet (peace be upon him) said to him, “Go back and perform wudhu well.” And in the narration of Tirmidhi, “Go back and perform wudhu well and repeat the prayer.” So it is mandatory for him to repeat the wudhu and repeat the prayer.

However, those who prayed with him (if he was leading the prayer) are not obliged to anything, as their prayer is valid.

And Allah knows best.
