The single session I was referring to was the clay + Cleaner + sealant. I think the polishing is included sa full detail session na 2.5k.

Naisip ko na din yan bro. Mas mura talaga ang optiguard kasi when you avail of the full detail session, there will come a time that you will be needing maintenance and based on experience, this is done 3x to 4x a year.

IMO mas mura Optiguard vs having single sessions.
