The below is a paragraph directly from the manufacture website. To me, it is misleading, directed towards the general public and discounts what a professional detailer brings to the table. Obtaining a perfectly polished surface in the least amount of time possible was a primary aim of the...

Heat used to be more of an issue as compounds had shorter working times, rotaries were used at higher speeds, and people were relearning how to use rotaries on newer paints. Just as DAs have come a long way, so have rotaries. I don't have the mindset that you should only do detailing one way. My...

Not missing the point, I'm saying could have avoided it by preventative measures. Taping vulnerable edges is still necessary for the same reason whether or not you're using a DA or Rotary. We are also way off topic but I figured I'd entertain the heat issue or non-issue for a little.

Tape off vulnerable edges? Doing this will also protect the pad from damage too.

Are you sure it was burn through and not more of a scuff from catching the edge? Most rotaries operate under 1000 rpm for todays materials, so they do actually stay pretty cool. If you are cranking up the speed then you are being negligent in the first place. I was going to make a video but I...

A split second? Where do you get this information? Which rotary, being used correctly, can produce enough heat that fast?

I might do a video or look for a video online about burning paint. As you said, you've read about it, and have seen it. But do you know what it takes to produce it? As DA's have gotten better with material and product, so has Rotary. Rotaries aren't used at max speed anymore. Again, maybe I'll...

Is heat completely unrelated to cut? Or can it be that the two are just not positively correlated? Can a long throw or forced DA produce as much heat as a rotary? How much heat does it take to burn the paint?

Of course, not all jobs require that much compounding, and if you can achieve results in one step, efficiently, then you should take it. But also consider how long you are spending on your single step. If it takes you 20 minutes to work one panel in a single step compared to a 2 step that takes...

you have to remove the same amount of paint, regardless of method, to remove the defects

Mike, correct. I am talking about using a 2 step process for the correction work. Step 2 remains the same in both instances, a DA that removes the rotary work and finishes down well. The variable here is step one. For a car that needs heavy compounding, grab the Rotary or grab the DA to make...

I have not rephrased MY question, I have only asked to confirm if/then statements, provided others input be true statements I gave my opinion in the first post.

Also, it is a misconception about a rotary EASILY burning paint. If you have not done any testing for yourself, how can you make this claim?

1 - Could your compounding have been done faster with your rotary? 2 - Losing focus with a DA can cause dings, scratches, pigtails, etc. so we are not considering human error. So leave burning out of this. 3 - I have already stated that you should not compound and leave unfinished. So comparing...

Mike, in your opinion, would a Rupes DA, long throw, have gotten the paint leveled in the same amount of time (start to finish) as the rotary?

I am just pushing hard questions to get definitive answers.

So if this statement is true, then is it correct to say that using the MKII in the first step does not actually save you time because it doesn't matter what tool it is, only the pad and compound combination? And since it is cutting at the same rate, given the cutting material, it is just as...

So if I rephrase and say - "using an MKII, you will need to be more conscious of clear coat levels than if you used a rotary because it cuts through clear faster" is a correct statement?

I have already pointed out that this does not pertain to my original discussion as this is a one step and we do not know the before condition. I have already agreed that if it is light swirl removal, a single step DA is first choice. But we are discussing a 2 step with compounding being the...

We aren't using error in this discussion, so assume the operator knows how to use a rotary and doesn't heat the paint beyond damage.
