Alright. Having done the polishing a few times since December (with today being one of those days)... I figured something out.
Speed 5 is the worst on this device. Maybe you can do 5.5 but mine seems to do either 5 or 6. (not much of an in between half notch) At 6, it just cruises through and this is where it *finally* makes sense as to why people use this freaking thing.
At speed 5, I spent well over an hour on the door panel and I'd still see swirls/spiderwebs. I couldn't believe how much time I had put in today. Finally I get to another panel and I put on hearing protection (because this thing is way too loud to use without them) and crank it to 6. Boom, the thing takes off like a rocket. Spinning super fast. Wow! The compound is flashing up almost immediately! I spend maybe 5-10 minutes polishing the panel at speed 6... It did better results than the other panel at speed 5 for an hour.
Stay at speed 6. One word of caution though: I exploded a pad today. It had started smoking a couple times while on speed 6 (couldn't tell it was smoke from burning and not just smoke from throwing compound) and then it exploded violently while working on the car. It started smoking to the point where I was like, "Woah that's definitely a lot of smoke, pull off." Because I didn't want to burn my paint... but then it just sped up even more because there was no pressure and the pad just started throwing chunks. Completely ruined.
So, speed 6 is where it's at but you definitely need to play it safe. I'll be doing more of the car tomorrow at speed 6 and report back how it goes. I have a really good feeling about it though. I'll probably do speed 6 and use the ultimate compound on the rest of the car (because it really takes soooo much less time to do now) and then polish the rest. I'll try to seal/wax then too but no guarantees.
Definitely has done a dramatic improvement to the workflow. That said, this car's paint is so freaking difficult to work with. Even polishing the heck out of it, there are still fine scratches that are seen in the daylight. Guess that's where polish will do its magic. Take out the extra fine stuff that you don't see as much.
I also need to use my paint that I bought and the clear that comes with it to repair all the chips.
