I just got a PC 7424 buffer. I read how to use it using this link, I don't have any questions about that. I was just wondering if you guys had any tips specifically for using it on Integras, such as around the spoiler and lights.
Mask off anything you don't want polish on and just be careful around the spoiler. That's really all there is to it. My backing plate is a little smaller than the pads I use and that gives me a little bit of leeway around the spoiler, but not much. What I usually do is put a towel between the grey part of the polisher and the car so when I'm going up against the spoiler it doesn't vibrate along it or anything. When I'm getting serious about polishing I just remove the spoiler so I can get everything. I only do that for show prep though. Not for normal detailing.
