The last time I did the G8 i spent 22 hours on the exterior. There was a lot of tar and overspray on the hood, fenders, and windshield so it took a while to clay. Using a PC also takes FOREVER if you're OCD like me. I did SSH, SH, FMP, MSS, Brilliant Glaze, and Americana. Did this all over 2 days. The interior took about 6 hours. most of the time was spent trying to get every spec of sand out of the the carpet with my POS crapman shop vac.
