What Will BURN THROUGH First? (Dual Action, Rotary or Forced-Action) | DETAIL MYTHS DEBUNKED

[@GardenCatsTV]

Awesome video it actually makes since though because typically you run a rotary with a wool pad and the reason why amateurs use a DA is to not leave swirl marks not necessarily because they are worried about burning thru clear coat i would like to see this done again instead this time have the rotary with a wool pad and the other 2 with a heavy cutting foam pad because that is more realistic i would also like to see this done outside in the shade in summer because come guys, you all know better than to be polishing in direct sun light lets not be dumb awesome video i would have lost some money on a bet to.

Isn't the major benefit of a DA Polisher that it will slow to eventually stop when wedging in edges or over pressure is applied? That along with the random nature of it's movement allows it to hide the more amateur polishers mistakes?

Correct, this test is fun and interesting but in real world use DA is probably better for most people. Rotary is arguably best for people who know what they’re doing and are skilled.

[@benruthlessburger8905]

Do you guys think the weight of the da cause it to break through first?

[@rickvandijk9916]

Very late answer, but I imagine it is the lack of downward pressure applied on the machines combined with the exponentially larger mechanical damage introduced from 2 actions and a much higher RPM from a free-spinning DA. I don't know the specifics of the machines used, but forced rotation/gear-driven machines have smaller throws than free-spinning DA machines, which decreases mechanical stress when all other factors are equal.

[@stuartlambert5059]

Forgive my naivety, but surely that means that the DA gives the required finish quicker? Once you have the required finish you just stop? Or am I missing something?

[@gregkimura5906]

Makes sense if you're looking at the speed of the wheel. Rotary spins with no other motion. DA will cut faster, due to additional movement in the x-y axis. Ditto for the Forced Action. What if you used all the machines on the same setting (for example, use setting 4). Then use a wool bonnet vs foam. Which would cut the fastest?

[@ccbowers]

No one mentions that the rotary pad is also smaller, causing less movement across the surface, but especially at the edges of the pad, where most of the action happens for rotaries.

[@Mercenercen11]

Da will NOT cut faster, this video is just spreading false information. A rotary is used to buff sand scratches out of paint, an orbital is used to polish the paint.

[@gregkimura5906]

A DA stalls, but a rotary doesn't. You put pressure on the rotary and it will cut and burn through clear. When you put pressure on a DA, it'll stall out = no cutting action. Watching this video proves that a DA cuts faster if it doesn't stall, however In the real world, you put pressure on the machine. A DA will stall, but a rotary won't, so it will definitely cut faster.

[@gregkimura5906]

The other thing is that you will burn the paint easier with a rotary - in real life. Someone who doesn't know much about polishing can get in trouble with a rotary. Keeping the pad in the same spot, using a wool pad and pushing down - yes, you don't need 10 minutes to cut through the clear. @@Mercenercen11

[@autoappearancespecialists]

Rotary and forced would definitely break through first

[@836dmar]

I wondered why they didn’t equalize the weight as they are likely not the same. Since they were testing potential to break through with identical pads, compound, and rpm, that could be a major variable. Same with tests of temp, thickness, and IR camera. Weight differences could change any of those. Still interesting - just a little flawed as a true test.

[@bobstorr4986]

@@836dmar I’d say equalizing the weight would invalidate the test. The idea is which machine on its own would break through first. By simply being lighter the rotary will break through last. And generally a rotary will be lighter than a dual action or forced action. Someone new to polishing using each of these tools and applying equal pressure with each will likely burn through with the da before a rotary would. Real world though, I think someone new would likely crank up the speed on a rotary due to impatience and more likely burn through because of that.

[@Bananovskyyy]

@@bobstorr4986 Also take into consideration how deadly rotaries are on panel edges when hit with the very edge of the pad. The edge of the pad is what rotates the fastest and has the most cutting power. Newbies hitting/letting the polisher skip off onto an edge can burn through it in seconds. I burned through with DA once in 4 years of polishing cars daily and it was on an edge (on my car so no harm done) which i sanded two times then polished with a heavy cut pad and compound. Burned through with rotary on a lot of test panels when i was learning. The test has nothing to do with how it works in real life, DA polishers are way safer because they slow down or outright stop their rotation when you hit an edge or a dangerous curve. Also they move around the edges in orbital motion, not constantly rotating and grinding through it.

Your test didn’t separate for the machine weight variable, and pad pressure does influence cut ability, yes? Is the rotary the lightest machine?

[@carlos.teixeira]

@@lukefernandez3492 If you really want to know and compare specific trait for each type of machine, then you would control for weight too. Because all machines available in the market have different weights, for each machine of the same type you would've got different results all else the same, so that will skew your results even more. You cannot compare anything without removing all bias, you just needed a heavier Rotary and all your conclusions would be wrong. I don't even care about your results, I just don't agree at all with your methodology. And if you're going to debunk myths, you better stand by your method.

[@robi4387]

And how is it going 2 years on

[@bpsdetailing8822]

Pretty interesting! The weight of the machines is a major factor in a test like this, so sadly this test doesn't really mean anything (unless someone owns the exact machines used in the video and polishes without applying any weight to the machine when polishing which is almost impossible) The machines should be running with the same force or weight to make the test accurate. Weight should have been added to the lighter machines to match the weight of the heaviest machine. Even zip lock bags of sand taped to the lighter machines would work. The rotary machines are generally much lighter than DA machines - DA polishers are probably twice the weight of the rotary.

[@daveyh8s]

I really think you’re right about the weight of the machines. Years ago I used to work in car production and we were using air powered buffers that weigh a ton and we were burning paint almost daily. I guess fresh paint , wet sanding and heavy polishers don’t mix very well lol.

[@SNELLERIZED]

A couple major flaws to the test here. Had you primed the pads across the entire surface area, as we do in real life, the lack of migration to the edges of the pad would not have been the factor it was, greatly affecting the outcome of the test. Also, what is the weight difference of the heads of the machines? Unless that was the same, you didn't accurately compare the cutting effectiveness of each type of machine.

[@soul_in_a_fishbowl]

The weight is the very obvious difference here, as friction is a product of the friction coefficient and the normal force (downward force) on the object. Because dual action polishers require more mechanical parts in the head, they are going to produce a higher normal force on their own. This isn't necessary an accurate representation of which one will burn through faster unless they were to compensate for the lower normal force on the rotary (plus this isn't really how a polisher is going to be used in the field).

Alright man wtf... It's in the pad/compound and the user. I would hate to see people in mass swapping to rotary thinking it's safer or even as user friendly as a DA. They would finish with their blue car with a once orange pad looking blue... The guy with the rotary knows when to back off pressure and the importance of keeping the machine moving, taking advantage of its advantage: SPEED. It's faster with a rotary. It's a scalpel. The rotary doesn't slowdown the more pressure that is applied! It keeps cutting and cutting so keep moving or you'll ruin paint. I was surprised lbs pressure wasn't really measured and based solely on the weight of the machine. These are all different machines. Add 8lbs of pressure on one spot at cutting speed for 10 seconds and see the real world difference. What I noticed was the DA was mostly stationary. The rotary was working in passes and rightly so because if not that thing would burn. You'd have to mount each machine with identical pads and compound to a robotic arm which applies equal lbs pressure and programmed to move or remain stationary to gauge real differences. People aren't machines. Practice rotary on some old hood in the backyard because it's a different animal. You can literally sand wood with it with the right attachment. Try sanding wood with some old porter cable.

[@Robbie-mw5uu]

@@GreenWitch1 is it cordless or corded? the battery ones are heavier

[@rtd9153]

The improvements with today's DA polishers; with the increased power, long throw, improved pads, forced action; has allowed them to equal and surpass the rotary in regards to cutting now. However, it takes a quality DA such as a Rupes or Flex (etc) to do so. Otherwise, the vast majority of DA's could never outperform my heavy Milwaukee rotary with cutting. I've buffed well over 10k vehicles professionally (14 yrs, retired) and have used both. The improvements to the DA's, in regards to power, has been very impressive. The rotary is still superior at finishing though.

Okay so what’s the difference in DA vs forced I’m confused lol

[@marc-andrelaplante5505]

What is the rotary RPM you were using ?

[@jules198625]

What means when polishing you have same color paint on pad?

[@KiaTia09]

Great vid how do you like that paint thickness gauge?

[@ryancaunce3142]

Best video ever!! Truly well done

[@GstarCurtis]

Amazing and interresting video! I have no idea how much cutting power said compound has, but what about Meguiars M101 or M100?

[@nicksdragon6929]

I think showing a typical 10 pounds of pressure would have benefitted the test. In addition, I believe this test gives a false sense of security to those with little experience. And the easiest way to do that would be to strap on 10# flat weights.

[@jacobusdegroot7557]

I never heard any mention of how much throw each machine has?
