Well don't quote my response if you don't want to address me. This is the only detailing forum I have ever been on where people are just dicks. Guess I'll stick to the other venues and just troll useful posts here.

He quoted you saying that the OP used a rotary and got two black cars to perfection, so the OP MUST know how to use a DA. (You stated how it takes practice to use a DA correctly)


He was NOT stating you used a Rotary.


Just making sure you understand that he had no smart ass comment towards YOU.
 
I wonder if my 15 mk2 is faulty? It seems to stall quite easily. I also have 21 Mk2 with 5" bp, Duetto and Mini and they all have washer mod(not mini offcourse). My 15 MK2 stalls more than my 21 Mk2 and Duetto, it just seems under powered. Anyway i love my 21 and Duetto. Duetto with washer mod is really an amazing tool!

Heck, I like the non modded Duetto!

However, I had to mod it a few weeks ago to chop away at some really tough clear coat...
 
I still haven't marked my Boss backing plate and it bugs me because I'd like to see a definitive line when I'm polishing without having to overthink whether It's actually spinning or not... Where can I get the best marker? Home Depot? I just want 1, not the costco 50 pk.
 
You can get a Black Sharpie pretty much at any convenience or grocery store.

I've got a bunch of black Sharpies here... But the outer part of the dang Boss backing plate is Black instead of yellow... NormL Sharpies don't work to mark it like they normLy do on typical Lake Country backing plates... I've been told to buy a white Sharpie. But all I've seen is 5pks last time I checked.

I wonder if womens white nail polish would work.. But I don't wanna rape my backing plate and wind up having it look horrible. Lol
 
they also sell silver ones (sharpies) as well. you can also try using a piece of colored tape (blue, tan, etc,)...

Yes I believe the silver metallic 1 is the best recommended.. I don't think any sort of tape would adhere for too long.. If you look closely there's actually a black stripe built into the Boss backing plates, but it's impossible to see while polishing. Not sure why they even decided to include it. Minor gripe, but still..
 
Can anyobody answer to my guestion? Should 15 Mk2 stall more than Duetto and 21 Mk2? If not, then my unit is faulty.

Hard question to answer without seeing it in person - will depend entirely on the depth of the curve or protrusion thats causing a rotation stall, your technique, etc.

If its just on a flat surface, no, but you honestly shouldn't see stalling with any of the tools listed on a flat panel unless you're pressing too hard or running the tool at really low speeds.
 
Dylan,

Between the 15 & 21 MKII, which polisher is less likely to stall?
 
Mark 2 with a washer mod should have no stalling issues. It would have to be a pretty dramatic and serious curve.

The original es models with no washer mod even on 6 was stall city. Even the new mark 2 versions with no washer I found them to stall like crazy. Infact my father hated the mk2 we bought prior to putting the washer mod in.

After the washer mod my father and I love the machine. The 21 mk2 and g21 is very hard for me to get it not rotating.

Adjust your technique if I have no issues with a 21 (larger orbit less opms) you should have no issue with a mk2 15 (smaller orbit more opms)

Another thing I would check for is check your "washer mod" you might have not installed it right. Make sure the shroud and the plate is properly spaced.
 
A few suggestions : Start the polisher on the surface. Dress the pad, then add polish first then prep the area that u r about to polish without starting the tool. Like a 3 square foot area. After the surface prepping has been completed and with the tool flat on the surface then start at 1. After a few correct passes move up to 4 or so. Keep the polisher flat during all passes. Stop the polisher while still on the surface.

Answer is going to be pretty much the same as above - hard to say. Neither will stall on a flat surface, it would be entirely dependent on the degree of the curve or protrusion causing the stall, speed of the tool, pad being used, compound being used (some compounds lube the surface more than others).

As a general idea the 15 should stall less in deeper curves due to the smaller orbit, higher OPM, and smaller pad as all those things mean it will be less effected by the panels curves, but thats not a hard and fast rule.
 
Well my 15 mk2 stalls easily and 21 mk2 works much better. I think im gonna sell my 15 since i have mini, duetto and 21 mk2 and also 5"pb fpr that. 15 is bit smoother but 21 is alot more powerfull

There is a video of my 21 MKII vs 15 MKII. My 15 harly spins that white Rupes pad, my 21 have no problems whatsoever and even my Duetto performs a lot better than my 15 MKII. It has been like that since new and i have done few cars with it. Faulty unit?
