    Re: Redesigned G21 and G15 Polishers

    They`re coming in very competitive at that price point at $240/$250, which is much less expensive than the previous gen when first released. Bit surprised they`re dropping the BOSS nomenclature I was not expecting that, but I do like this body design a lot. Trigger on these will be a progressive variable speed trigger which differs from the on/off trigger of the G9. New cooling integration on the backing plate, and this feature has me very interested as well:

    "Balancing the combined weight of a backing plate, buffing pad, and the liquid on the pad translates into less vibration and a smoother running machine. For instance, microfiber pads generally weigh nearly twice as much as a foam pad so fine tuning is beneficial. Our innovative Weight Optimization System consists of three uniquely engineered fasteners, each weight-matched to a Griot`s Garage pad type to ensure you`ll enjoy best in class performance from these machines."

    And the below pulled from the online manual: https://vidweb.aws.marketlive.com/gr...0915_10921.pdf

    G15/G21 WEIGHT OPTIMIZATION SYSTEM

    There is a proverbial dance that occurs between an orbital polisher`s counterbalance and the combined weight of a backing plate, buffing pad, and the liquid on the
    pad. Balancing this combined weight translates into less vibration and a smoother running machine. For instance, microfiber pads generally weigh nearly twice as much as a foam pad so fine tuning is beneficial. Our innovative Weight Optimization System consists of three uniquely engineered bolts, each weight-matched to a Griot’s Garage pad type to ensure you’ll enjoy best in class performance from these machines.


    So a way to fine-tune the balancing of the pad on the spot which is going to work great for working with a variety of different pad types. Very cool stuff coming out at Griot`s this year, can`t wait to hear some feedback from the testers.

    Re: Redesigned G21 and G15 Polishers

    I`ve never used one before...but am interested, especially at that price point for another `back up` machine if needed. Ergo`s can make all the difference!

    I still need to trade in one of my GG6`s!!!

    Thanks for posting!

    Loach- Hey, that`s interesting about the progressive trigger, thanks for mentioning it.

    I personally miss my Original G21 modded with a Katana BP, that was the mostly beastly DA I`ve ever used. It was like a hot knife through butter with Gel coats!

    I`m not expecting any issues w/ my older 15 & I wouldn`t except any major problems w/ the 21 as well. For the newer 15/21`s yea I could see the cord connector to be a issue. Just looking at the hand grips of the two says the older machine is more ergonomical. Not near a issue if you bought a used Rupes & had to try & get it repaired/redone if you bought it 2nd hand or pass the one yr warranty, enough thou I like the duetto......

    Re: Redesigned G21 and G15 Polishers

    Heh heh, all these newfangled polishers with killer specs are possibly gonna kill lots of paintjobs through over-thinned clear. I see *so* much of that in my area already, clear as day...you can often tell exactly how the (over)polishing was done.

    Not that I mind having the extra power to speed things along, but I hope everybody remembers to know when to accept "enough better" instead of always aiming for Autopian Perfection.

    It’s good someone’s got to compete with flex and rupes. The lifetime warranty is a nice tickle

    Now I have to add a Paint Thickness Gauge (PTG) to my detailing tools! I do think, though, your point is well taken, especially on newer vehicles and recent paint/clear coat techniques being used in the manufacturing process.
    It is also the reason Mike Lambert suggests using the new Griot`s Garage G9 polisher with its not-to-aggressive 9mm throw on thinned clears of multi-polished older vehicles OR the fore-mentioned newer vehicles. The "problem" being unless you measure the paint/clear coat on a vehicle, how do know. And if you do not, your run that risk of burn-through or least reducing the life-expectancy of an exterior surface. It is a scary scenario, especially in the used-vehicle market. MAYBE the Car-Fax needs to include paint thickness readings... just sayin`!

    Re: Redesigned G21 and G15 Polishers

    Lonnie- It`s been forever since I bought a vehicle (what a change!), but, for the last however many, when I did I always took my ETG [INSERT usual rant about how I hate mine HERE]. Even if sections were repainted/other complications, it gave me some idea about what I was (really) buying.

    Thinned paint was the primary reason I passed on at least a half-dozen (!) ex-LE Crown Vics; resellers always overdid trying to undo all the in-service damage...

    And yeah, I never use any of my more aggressive polishers/pads/products on our thin-paint vehicles. On the `93 Audi I did *one* last correction when I got it back in `08...doing more damage ...which got it good enough as long as nobody touches the thing except for my washes.

    Way back when I had that (new) POS `01 Mazda MPV I was shocked at the upon-delivery/untouched paint ETG readings; one Autopian C&B-level correction would`ve destroyed it long-term-wise. I had maybe three microns to spare over its service life.

    Not to pick on *you*, but I for one wish we`d all quit mentioning "burn through" since the paintjob will be compromised *WAY* before taking off that much. Yeah, I`m doing OK with that `93, but I don`t leave it parked in the sun for hours either.

    I gather you find your version of the 3" satisfactory...or even better than that. It *is* a lot more compact than the G8.
    Oh for sure! I do wonder why so many complain about it. Then again, I never used the v1 model myself.

    That is interesting. I wonder how effective it is. Now I`m curious to see how it would "feel" during polishing.

    This is the first I`m seeing this info. I`m assuming GG sells these additional bolts?

    Re: Redesigned G21 and G15 Polishers

    I haven`t looked, but I`m guessing they will sell them, or more than likely, include them with the polisher units. Much like how they include a washer for the "washer mod" with the BOSS G15 and G21.

    Re: Redesigned G21 and G15 Polishers

    So I am assuming that the user changes out the screws based on the pad to be used from the table, much like changing weights in a Porter-Cable Dual Action (PC-DA) for balancing of backing plates and pads of a diameter than the standard from-the-factory 6" plate.
    Are those screws slotted countersunk flat heads, slotted pan heads, or Phillips head screws, hex-keyed countersunk screws? Yes, the drive tool used to remove and tighten the screw head makes a BIG difference, especially if you need to do this often enough. Anyone here KNOWS what happens to slotted screws that are repeatedly removed and tightened; the slot strips out. Does not say if they include a tool to do so, like a hex key, or if it is a special drive, like a Torx (Those special star-shaped recessed holes in screws that GM uses; my preference for constant removal/tightening. Captain Obvious, the engineer!)

    Re: Redesigned G21 and G15 Polishers

    That is what I take: match the bolt to the pad. But just a bolt/washer, not so much a big chunk of counterweight

    Not sure about the drive method for the bolts for the WOS (weight optimization system). When I took apart my PC recently, i did find a mix of Phillips and Torx, and one hex bolt where I needed a socket.
