Meguiar's MT300 Dual Action Polisher

Re: MT300 Dual Action Polisher

ok another question I haven't found yet. I have the DA G110V. Have loved it since I bought it 3 years ago. Huge difference over the old orbital buffer I had, lol yes orbital buffer. I want to keep my G110V and add the MT300 for the grunt work, use my G110v for the smaller 3" pads and areas that the 5 or 6" pads cant' reach. It'll save so much time not having to stop, take the pad off, remove the backing plate, put the smaller one on, center the pad and then get back to polishing etc.. Be nice to just grab the second polisher all set up ready to go and keep on moving.

Anywho, question is I have is do the G110V backing plates fit on to the MT300? Here are the ones I have S3BP, Lake Country 3" DA Backing Plate, S6BP, W67DA, W68DA. Will these BP's I have work on the MT300. Only one I do need is the 5". I'm ready to order the MT this weekend so hopefully I can get a quick response. Thank you

Re: MT300 Dual Action Polisher

The W67DA works fine with it.

Re: MT300 Dual Action Polisher

So if that works on it, that means all the BP's I have will work as the thread is the same on all of them. Now will the W67DA allow the new thin foam pads to attach properly with the hook and loop system? or is that why they have new bp's with the thin pads? Just want to get everything I need to work properly and again am buying everything this weekend (more than likely today) so I get everything going

Yes. I used the new foam discs on a W67Da and the MT300 with no issues.

Re: MT300 Dual Action Polisher

Are you using the 6.5" thin foam disc or the 5.5"?

Re: MT300 Dual Action Polisher

5"

Re: MT300 Dual Action Polisher

Can this tool be used professionally, or would you recommend buying another one for daily usage?
Where would be the most economical place to purchase your product?
Thank you.

Re: MT300 Dual Action Polisher

I don't see why it can't be used professionally? Is there any reason you would think it's not to be used by pros?

Re: MT300 Dual Action Polisher

Last weekend, I used my MT300 to polish my car's hood (light marring). Since my 5'' pads were still a bit wet from being washed, I tried Meguiar's 6'' thin foam disks mounted on a 6'' backing plate (an LC plate, IIRC). I used the yellow polishing (two passes) and the black finishing (one pass), both with HD Polish. The yellow produced a nice, clear, LSP-ready finish. The black pad added very little, though it was only one pass at a slower speed (3800 OMP, just experimenting).

Regarding vibration, I did not find the MT300 as smooth using the 6'' pad/plate combo as the 5'' combo. Nothing terrible, but noticeable (mostly at the trigger grip end, for some reason). Power, however, was fine running the 6'' pad. I had no trouble keeping the pad spinning; the MT300 is very torquey/powerful. Compared to my old PC, the MT300 corrected much more quickly, and was easier and more enjoyable to use. It was well worth the upgrade.

Re: MT300 Dual Action Polisher

I like the tool but was just wondering if it is meant to be used on a daily base? Or would a stronger tool be advised for professional usage?

Re: MT300 Dual Action Polisher

I'm getting back into detailing since I bought a new car and have me eye on this polisher. My question is regarding paint safety for a noob like myself who has never used a DA polisher before. The other DA's on the market will stop spinning with too much pressure to prevent paint damage but it sounds like this one won't. Is that something I need to be concerned about if I purchase this machine?

Re: MT300 Dual Action Polisher

If you're concerned about using too much pressure and damaging the paint, you might want to do a bit more research into the use of pressure with a DA as part of the general technique needed to obtain optimum results with one.

Any DA tool, simply by virtue of their design, will stall pad rotation if tipped on an edge. Some will stall with only moderate downward pressure even with the pad flat against the paint, while others can take some serious pressure and maintain pad rotation. But here's the thing - just because they will keep the pad spinning under heavy pressure doesn't mean you should be using heavy pressure. You definitely want a tool with enough torque to keep the pad spinning during those times when you need to get really aggressive, but in no way does that make the tool dangerous for a novice. In fact, it more likely means the novice will be able to keep the pad spinning even when he tips the tool a bit, allowing him to keep getting defect removal while sharpening his skill set. One of the most common faults we see of new DA users is them struggling to keep the pad flat, or the center line of the pad in contact with the paint on contours. Even the simple contour of a hood sloping downward toward the grille catches new users out; they tend to tense up their upper body and move the tool in a pendulum motion, lifting one side of the pad off the paint and stalling the pad. Stay relaxed, pay attention to the curves of the body panel and flow with them. A low powered tool won't help you through those spots and frustration will set in pretty quickly as you struggle to remove defects.

I have next to no experience with polishing, last weekend I took the advanced class at Meg's HQ. This DA, along with every other out there is idiot proof. They had test panels out for us to practice on, I pushed hard, I titled the MT300 on it's side and pushed down, you won't do any damage with this machine. Even intentionally trying it's not going to happen. I applied a a lot of pressure, far more than you'd ever use in the real world. Then I held it in 1 place, it slowed down to an almost stop. After 20 seconds I lifted it up and felt the paint and it was barely warm to the touch. Michael explained it well, I'm commenting as a non Meguiars employee that you should buy this machine and not worry about doing harm. If you look on Youtube for a detailer called Junkman he has a video where his 6 year old niece is safely using his DA on his Vette.

DA's are truly amazing machines for how much correction you can get with one, and how there's literally no chance of causing any damage.

Though the MT300 is a torquey/powerful DA, it is safe and user-friendly. If you use the correct pads and polishes (i.e. the appropriate amount of cut for the paint condition/thickness) and proper technique, you shouldn't have any problems. Can you do damage? Sure. If you are polishing thin paint with an aggressive pad and polish, you could go right through the clear. Detailing 101...always use the least aggressive approach first.

Re: MT300 Dual Action Polisher

Thanks for all the responses. I will continue to read up on proper polishing technique as well as compare the pros and cons between the MT300 and the GG6, which are the two DA's I'm looking into. I love the design of this machine and am very much interested in the less noise/vibration. As a new dental graduate, I'm probably going to lose my hearing regardless due to my profession, so anything that can reduce harsh noises on my ears would be beneficial lol Also, I'm hoping the decrease in vibration, compared to the GG6, will reduce muscle fatigue in my hands, arms, and shoulders since they're my money makers during the weekdays!
