Good polish/wax to get swirls out

Ok... It is a general guide to always use the least aggressive approach to get the job done. The amount of clear on your car is finite and every time you compound the car... you are taking layers off your car. Most vehicle paint film systems (127 - 178 µ) which comprise a Primer coat of 2Mils (50 µ) and a Colour coat of 1-2Mils (25 -50 µ) and Clear coat 2-3Mils (50 - 75 µ). To put it another way, normal paper is about 100 microns so the average new car has a total thickness of just over one sheet of paper.
I would recommend you try an approach that is less aggressive first prior to M105. Look into a medium polish like Menzerna SIP , BlackFire SRC, or my current favorite CarPro Fixer. CarPro Fixer is a polish that is pad dependent so you could elevate the aggressiveness by simply changing the pad to a more aggressive one. For over the counter, try Meg Ultimate compound and Polish. It is much more forgiving on your first time out with a DA. I hope this helps.... Good Luck.

So I did a test on my trunk this Saturday. I did A clean/dry, clay bar, and M205 with just a finishing pad. I think I need to do my polishing pad and then the finishing pad and it would get the car looking great.
My only issue was that I did get some halogramming when I was done. It's not bad but is noticeable. How can I keep from getting this? Did I work the M205 too long? |

If it didn't then go to the polishing pad and try again. How many passes did you make???? M205 is a SMAT product so you could stop any time you feel appropriate. I normally would do the last 2 passes at the end with no pressure and slightly faster arm movement to minimize the effect you are referring to. Again... Good Luck.

Ok I will try that!
It got the swirls but not some of the finer scratches that I can't feel with a fingernail. I did 8 passes left to right and 8 north and south alternating. Then I wiped really lightly with a MF towel. I had good pressure on the first couple passes, lightened up on the next 3, an almost none on the last 2. |

I didn't think it would be enough to take all the defects out.
If I am reading this right.... you did 16 sectional passes. Generally 6-8 would be enough. How long did it take you to do that many passes and how big was your working area? Is the product drying up on you?? Your arm speed should be around 1 sec per inch with firm pressure on the first 4-5 passes. The last 1-2 should be faster than that with almost no pressure. Good Luck and remember to have fun doing it.

Working area was half of the trunk. It didn't seem to dry up at all. I went faster than 1" per sec though. I will give that a try. Have some time to possibly do the entire car Saturday morning so hopefully I can get at it.
Trust me I have too much fun cleaning my car |

With your machine, this is a time consuming process. You are probably looking at a 5-6 hours process (possibly more if you are doing a multi-steps correction) with this is being your first time out. This is what I would recommend to make it more palatable. Once you define the appropriate approach (which product, which pad, how many passes per section,etc) for the entire car and validate it through your test spots, do "start to finish" a panel at a time. You would correct and polish then apply your LSP a panel at a time. This way you could work on your car in sessions through the week or weeks rather than doing a all-or-nothing marathon. Like always.....Have fun and good luck.

I also use the Harbor Freight DA polisher and m105/m205 and have had great results. The key is to be very patient. Don't be surprised if it takes a week to complete the entire car instead of just a day. I still have not completed my entire car, and I started a couple weeks ago.

For those of you getting the HF DA, here's a 5" backing plate for it for $10. It just came back in stock on Amazon and cheaper too:
