So I've had my G for about 2 months. Always had these annoying water spot type marks on the clear plastic of the gauge cluster and by the analog clock. I've tried cleaning with a meguirs wipe before and 303 fabric & vinyl cleaner and invisible glass today with no luck. Any ideas how to clean this up?

 

May I assume you're refering to the plastic lenz on your cluster and clock? Meguiar's make PLASIX sold in most autoparts stores. Use a microfiber rag and apply a small amount gently to your cluster, and wipe off....waterspots gone! I keep this product in my cabnet for just such issues.
