In this 40-minute video, I discuss and show my technique for buffing complex curves and angles on the side of a vehicle. I discuss and show how to negotiate the various angles, dips and curves that you may encounter. The thing that I stress in this video is that you have to constantly pay attention to what the polisher is doing when you are working on areas like this. The sound of the polisher will constantly be changing (or talking to you as I call it), which gives you clues on how to proceed. It is this "talking" that the polisher is doing that will be your clue as to how much pressure to use and how to angle the polisher while buffing.

There is a LOT of watching that you need to do as I am working the polisher. Notice how I don't necessarily use a cross-hitch pattern of buffing like I would on a flat and open surface. Notice that I tend to use short buffing strokes in the dips. Notice that the pad NEVER stops rotating, which will happen if you apply too much pressure. You ALWAYS want the pad to rotate or the effectiveness of the machine will be greatly diminished. Watch and pay attention while learning!

Products and equipment used:

Orange 6" Hex-Logic pad (for a novice, a 5.5" Hex-Logic pad is a MUCH better, easier to use and preferred option).

Optimum Compound II

Porter-Cable 7424XP orbital sander (or polisher if you want to call it that)

16 x 24 Eagle Edgeless Blue Super Plus Microfiber Towel

Enjoy!

Thank you for the great video Junkman! It's very educational indeed. I too have a Porter-Cable polisher and I didn't realized it was designed to be a sander in the first place!

My question for you is, how fast should I let the pad spin when I set it to speed 5? Is about 3 rounds per second about right?

What would you recommend as a good car polisher that is more powerful than the PC (doesn't take as long) but is not too expensive? ($150 or less?)

Thanks again!

Watch my video series on machine polishing for novices.

There is no such animal. That's like asking someone what car can they buy that is exactly like a BMW but cost a lot less. There's a reason that a BMW cost what it does and you get what you pay for.

Good stuff love your videos been watching a bunch of them recently. Learned alot. Not sure if you have a video on it but what would you recommend for wet sanding a scratch I have like 3 not too deep scratches about 2-3 inches in length obviously polishing then sealing/waxing after

I have a better question. Are you planning on doing this on your BMW or just a piece of scrap panel from a junk yard?

So I should just keep polishing until there out?

I don't know how I missed your question. Whether or not one should wet sand on paint depends on one of two things. One, if you don't know when it is necessary then you SHOULDN'T be doing it. Two, if you haven't been shown how to do it then you definitely shouldn't be doing it. I have put out videos that show HOW to do it on a very limited basis, provided the scratch is VERY light. If you fingernail can feel the scratch, you NEVER wet sand that. That requires a repaint.

haha it's all good. I did a whole paint correction on my car minus the roof and I have like two scratches that I can feel with my fingernail and a few scratches that didn't come out after a 4 step polish in those areas so I'll probably do a very very light wet sand that part of the roof/hood. thanks for everything your videos are great. I need to do another detail to remove swirls from car washes they were hand car washes but they obviously did not take the same care as me doing it . just haven't had much time to do it myself.
oh yeah and thanks!
