I was removing swirls on my mom's car with a light-cut (orange) pad on speed 6 with 3M MG and it took me about 30 minutes just to do the hood. I was moving very slow with the PC, to the point where you could hardly tell the machine was moving.

I would like to be able to remove the swirls faster than this, so I am probably going to get one of the Poorboy's SSR products, or maybe one of the new Sonus SFX polishes. I want a heavier polish to deal with swirls. I plan to get a cutting pad for this step too.

Also, if I got a car with even deeper swirling, then it would take forever to do the whole car with the MG.

My uncle has a Mazda Tribute with terrible swirls, and he wants me to remove them in the spring. I want to make sure I have the proper products to do it.



Which SSR product is 3M PI III MG closest to?

Which Sonus SFX product?

Would the MG be adequate on a polishing pad to clean up any marring left behind by the SSR or SFX?

MG isn't really that harsh of an abrasive. On the âہ“unofficialâ€Â� abrasive list it is rated a 4 (higher = more abrasive) along with Megâ€â„¢s #80, although I think it removes defects a little better. Here are how the SSRâ€â„¢s are rated:

SSR1 - 3

SSR2 - 5

SSR2.5 â€â€œ 6

SSR3 - 7



Not sure about the new SFX polishes, but Iâ€â„¢d say itâ€â„¢d be close to SFX-2.



If youâ€â„¢re working on nasty defects try something with more bite like 3M PI III RC, DACP, SSR2.5, etc.
 
SSR2.5 is great with a cutting pad. I might give SSR3 a try since I deal with some cars that are in pretty bad shape in regards with swirls. IMO I would just get SSR2.5 and SSR1. If the vehichle you are doing is reeeaallly bad with "deep" swirls then I would give SSR3 a try.
 
I was just looking at the SFX line at the Autopia store...

I am considering getting SFX1 and SFX3, along with a cutting pad to use with the SFX1. if I had any marring left behind from the SFX1/cutting pad that was too deep for the SFX3, I could use my polishing pad with the 3M MG.

That would also work if you want to try out the SFX line. SFX1 will have a lot more bite than MG, and from the reviews I've read it seems good at removing defects. You're also correct in being able to fall back with MG on a polish pad if needed.... saves buying SFX2 if you're wanting to save a few $$$$.



Another consideration is buying some 3M PI III RC, that will give you a lot more bite and you already have the MG to follow up with.



Lots of polishes, lots of choices........

I haven't used either 1Z or SFX polishes but from various reviews and ratings I would say they are all in the same ballpark.



I personally like the 3M RC & MG because they don't leave any fillers, are easy to work with, and give good results. I do have some SSR1 and 2.5 on my Christmas list to try in the sun.



Reviews on the SFX so far seem mixed; a couple of users loved it and a couple had problems removing it. I'm sure it is a good product, and just like all the other polishes used here a lot of it boils down to what works best for you and personal preferences.
 
i just read the reviews for the MG, and it seems like people can remove all but the heaviest swirls with a cutting pad and the MG. If I used a cutting pad rather than a light-cut pad with the PI III MG, it would remove swirls faster right? I'm pretty sure that I'd have to use the MG again with a polishing pad afterward, but that's OK.
 
It depends on how hard the paint is and how bad the defects are. Using a more aggressive pad is always an option, but remember that MG is not all that aggressive. If I can't do much with MG and an orange pad I'll grab the 3M PI III RC.
 
If MG and an orange light cutting pad isn't cutting it I would move up to PI III RC on an orange pad. IMO this a better option than stepping up to a cutting pad with MG. Cutting pads are a last resort for me.
 
OK...One more question.

If was trying to prevent any induced micromarring, could I use the RC on an orange pad with better/faster results than I got with the MG?

Better and faster results, yes. Micromarring (or slight hazing), probably, but not that severe, and a follow-up with MG will take care of it in short order.
