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

Good to see how long it takes to break through the clear coat. As a newby, this is very helpful!

[@dralitahir]

I had bought a rotary as a beginner to polish my cars and I was returning it for a dual action polisher today. Watched this video at the last minute haha. Gave me confidence with my rotary. Will keep it

[@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?

I think since zero pressure was being applied (not practical in the real world), the DA broke first because the oscillating action may have inadvertently caused more friction vs the consistent behavior of the Rotary polisher. That's my theory anyway. Would be interesting to see the results with pressure and some identical movement. Regardless, this was an excellent video!

[@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.

Ricky Colón Hell Yeah!

[@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

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.

[@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. Interesting test none the less.

[@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.

[@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.

[@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.

[@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).

Hallo nice video which machine is better to learn and easier to learn and do not make damage..

[@seugeniogonzaleze9296]

Very nice test, thank you! Which DA was used by Yvan? How long the throw it had (15 or 21 mm)?

Lol I literally just bought your towels, they look like a great value and people are saying good things. It's funny the other big options had a lot of concerns like towel bleed, or being the opposite of lint free.

I use every one of them every single day even pneumatic ones. Except for force action pneumatic I don't know if that's even a thing... Anyways. I can tell you from personal experience that if you're applying pressure and using it practically a rotary will always cut more than a DA or a force action polisher. Especially if you're working on fiberglass or plastic bumpers. This also depends on the cutting compound you have as well if you're using just a fine polish then the da is going to cut faster because the rotary is just sliding over itself where the da is spreading everything out and rotating

Key for the win was the rotary was not running at full speed. Running slower kept temps down and let the pad do the work. If you run the rotary at a higher speed would it not burn through sooner? A new test for you, plenty of hood to test on! Agree that your test was trying to keep all the same speed and it worked to compare all correctly. My thoughts, right or wrong.

The Rag Company your test was 👌. The rotary has the bad boy reputation. Burn through is the issue and I suspect newbie users think to run faster and get the job done quickly. Most stay traditional and use wool pads, wimps use foam. Loved how Levi expressed his opinion in recent Q&A when to use wool or MF pads. Now I need to add rotary skills and buy my first rotary.
