We will be doing a nice job if weather gets warm. It has lead coated copper gutters. I told homeowner we constantly rinse copper and if there is a reaction it will turn back to the weathered patina. What happens with lead coated copper?

The SH will spot them. Keep them covers in water while treating around them.

Eventually but it could come back uneven and take a while

Test a area before you do the job. We had a job with lead coated copper all over a house. The home owner was a metal freak, everything on this house was metal. We started cleaning the shingles and the flashing (lead coated copper) around the chimnies turned black instantly as soon as the SH hit it. After discussing with the home owner what happen with the flashing we ended walking away from the job. The home owner was fine with the flashing because it was not visible and appreciated our honesty. Be careful

I get that, but does it return to the original patina the same way that copper returns to the original patina after a couple of months.

It should, however lead coated copper is just copper plated so be careful not to eat all the way through the copper finish.
