I use the Eco APC, just as in the video. Rinse down, spray with APC, and I use the lug brush in the tight spots. I did not have enough grime to need the wheel brush. Then I rinsed off, and closed the hood while I did the rest of the car. Once it was dry, as others have mentioned, I use VRT and In & Out Spray. On the Vette, you will love how VRT works on the air intake under the hood vent, and how well it works on all of the trim between the windshield and firewall. In & Out spray works great on the throttle body, and around the fuse box.
