Welcome to the Optimum Forum. Optimum suggests not getting Opti-Coat Pro wet for 12 hours, so you should be good. The hydrophobic characteristics should be in force. I suggest you contact the pro installer and ask them to review the issue.
I store the BRS in a covered bucket with ONR solution (about half way) and with my clay towel draped over - keeps the sponge and towel moist but not soaked. Occasionally I add to or replace the solution - I go by feel and smell, there's no timetable for frequency, assume it's dependent on bacteria growth.

Kristian, I've answered by email, but MDR is the less aggressive water spot remover (Optimum always goes from least aggressive to most in suggestions). If the Maguiars Wheel Cleaner is acid, it should work.
