M84 - no DA, rotary only.
M80 - great for DA polishers.

You may need:

- orange light cutting pad(s) - for swirls, scratches, water spots, oxidation,

- more aggressive paint cleaner - like Ultimate Compound,

- more pads - as they become saturated with the products and removed paint; black, white and orange are good.

+1 On what Greg said. You will need more pads.

Orange pad and UC should get you the results you are looking for.

Thank you so much Greg for the advice. Okay, I'll search for orange Pad and Ultimate compound later. Like you said I'll try white pad with M80 first, if the result is perfect then I should not need to buy orange pad and UC By the way is it allowed to polish my car with M80 several times. If I do so, do the paint will fade? because I think the paint is not hard.
Do you think the defect will be removed if I only use M80 and PC?? how long should I apply this product in one section? how fast I apply M80 per section?

It looks like I have search these two product again. Hope I find it soon. Still search for the cheapest
In Indonesia, finding this product is so difficult and very pricey I guess. I'm detailing the car that is not high class (like Mercedez, Audi, BMW). It's just a regular car (ISUZU New Panther 2008) so I guess it would be too much to shop for USD 400 for a regular car, don't you think so???
Well this is my first car that I bought with my own money, so I will try to take care of it the best I can

The full swirl removal with M80 will depend on your paint hardness. In worst case scenario you'll improve them rapidly by cutting their sharp edges making them almost invisible.

M80 is very user-friendly. It has good polishing oils so it will restore gloss. With white polishing pad and PC 7424 XP you can use it more than once if the first application didn't bring full satisfaction with the results.

how fast should I set the polisher's speed? and how fast the movement I make on the panel?? really have no clue about this...

Jefri, I hope you are re-thinking the use of M84. You've been advised by Murr, Michael and Greg against it's use with a DA buffer.

The white pads I have are very hard, if yours are too then it sounds like, based on the advice of others, you will be making matters worse. Specifically Mr. Stoops said, "While M84 is much, much too aggressive for D/A use, and probably overkill in general for the defects you've shown us, there are a lot of products in between it and M80."


Greg's advice below is right on in my humble opinion. I've been using M80 on a recently painted Nissan and been pleased with the results.

I only offer these two bits of advice: listen to Murr, Michael and Greg and secondly do a test spot with the least aggressive method first. Although you may not have the products you need right now, you'll get them sooner or later. Be patient, fix what you can now, make it the best you can and when you get the other products you can make the finish the way you desire.

Spoken like the seasoned pro you are fast becoming, David. Excellent advice.

Hi David,
Sure I'll try with the M80. but if the result is not good, then I am afraid applying the third polish with UC will make the paint wear off (I think my paint is not to hard, not like on the high class cars (audi, BMW for example)
what do you think??
New Question---> after applying M80, what should I do then?? (check the swirls, wax or what?)
Thanks

Hi Mike I have some questions again
1. Can you tell me how to apply M80 on porter cable? I've read a thread "is it normal" that the M80 can dry too during the polishing process, how to avoid it? 2. Should I set the speed to 5?
3. Should I check for heat build up on my paint during the polishing? what should I do if the paint become hot?
4. How long should I polish each panel? Can it be finished in 5 hours for the whole body?
Like I said the paint is not too hard (you've seen the result by hands)
Still have a little confusion on this Mike.
Thanks

Hi Mike I have some questions again

Answers to your questions are in red below:

1. Can you tell me how to apply M80 on porter cable? I've read a thread "is it normal" that the M80 can dry too during the polishing process, how to avoid it? If you read through D/A Buffing 101 – An Introduction to the G110v2 (and similar) you'll see how much SwirlX we applied to the buffing pad - this is how you would use M80, too. M80 should not dry out quickly and should give you a pretty long buffing cycle. A couple of very important things to keep in mind when using a DA buffer:

• Don't move the pad quickly over the paint - take your time and move it s-l-o-w-l-y from side to side with overlapping strokes, then move up and down over the same are, still with overlapping strokes.
  
• The work are for each section should be no larger than about 60cm x 60cm or even a bit smaller. Working too large an area spreads the work over too wide an area to be effective
• Apply enough downward pressure on the pad to almost make it stop rotating - not quite, but almost. The pad does not need to spin quickly, but it does need to spin
  

2. Should I set the speed to 5? Yes, for defect correction you'll need this speed behind the pad

3. Should I check for heat build up on my paint during the polishing? what should I do if the paint become hot? This process should not get the paint hot enough to be dangerous, but it can make it a bit warm. When first getting used to the tool, every now and then just place your hand on the paint where you just polished - it may well be a bit warm, but it should never be painfully hot to the touch. If it is, back off.

4. How long should I polish each panel? Can it be finished in 5 hours for the whole body? This really depends on how bad the defects are, how soft the paint is, and what your expectations are. It may be possible to correct the whole car in 5 hours, but it may take 4. Or 6. Or 18. There is no set time for this as there are simply too many variables.

Thank you Mike for the advice, I forgot two more questions.
1. Can I use lake country white polishing pad (I only have 1 white pad and 1 black pad)? The black one will be used for waxing.
2. After applying M80 and clean it with MF towel and the result is perfect, the next step is applying wax, right?
Looking forward for your advice.

Re: Need some advice using porter cable and M84!!!

White polishing pad will offer less paint cut than orange light cutting pad but it will work. When removing swirls you need to remove small amount of paint leveling the area. The process with white pad versus orange pad will be slower.

Because you have only one polishing pad you need to clean it frequently. Use a clean terry towel to do so. Press the towel against the pad, turn the polisher on and keep it running for short period of time. It's called cleaning pad "on the fly".

After M80 you protect paint with wax. Slow down the polisher speed to setting 3 and you can move your arm faster as you just spread the product without any correcting job.
