I need to get a random orbital buffer, but I've been comparing different brands, types, etc.

Here's 1 that I looked at: http://www.northerntool.com/webapp/w...9667_200319667

It's considerably cheaper, but I'm not sure if the rpm range is too low for it to be effective. Being that I am not a Pro and I will only be using it 2 or 3 times a year on the car, I have a hard time justifying spending $120+ on one.

What are benefits to a PC versus other brands like Makita, or Milwaukee?

If comparing 2 random orbit polishers with equal rpm ranges, if durability is the same, are they essentially equal? The cheap side of me wants to buy a ryobe 6" RO buffer for $40, then if it breaks, I can replace it 3 times and still pay the price of a PC. (I know that it is inferior...so we won't go there)

Finally (i think) what is the safest rpm range for use on paint in terms of effectiveness that will not burn the paint?

Can anyone vouch for a cheaper product that is still extremely effective?

 

this is an octaneguy question. i started out with a griot's one so not
familiar at all with the porter cable ones.

 

random orbitals will not burn the paint easily, especialy below 5,000 opm. OctanceGuy recommends using more than 3,000 opm's for almost all PC uses. I just bought the PC a few weeks ago, and the results cannot be described using words, you truly have to see it in person to believe it.

 

One thing to consider is that even if two different models have the same "no-load" RPM, they may not behave the same when you actually put them to the paint.

A polisher with a stronger motor (higher amperage) will be less likely to "bog down" when you apply the required 15-20 lbs of pressure to remove paint defects.

I have an old Sears RO polisher with a fairly-weak motor (would have to go out to the garage to find the specific amperage). While it's fine for applying waxes and sealants, it's not up to the task of defect repair.

I have the Griot's polisher, and it's great, but like the PC, it's about $120.

 

with your purchase i would highly recomend OctaneGuy's dvd found in the NAM store. If you watch it and go to your car with a PC, you will know exactly what to do and what not to do. Really an awesome product.

 

Get a PC!! There are thousands of pros out there who will be able to advise you on a PC but another unit?? Who knows! Buying PC is like having the Polisher version of the Verizon network behind you!!!

 

oh yah, that reminds me. that's another detailing thing i need to buy
this spring.

 

I received a PC (7336SP) as an x-mas gift. It was the Detailer's Paradise PC and Pad package/bundle. My first project was the gf's abused 2001 Hinda Civic. Amazing tool the PC! If I get a chance, I will post some before and after pics.

I have used a PC prior to this, ala Octaneguy, so any and all knowledege I have gained is thanks to him!

 

congrats on the gift. it is truly a gift that keeps on giving....

 

PC vs ??? = PC vs Mac , and Mac wins out

And back on topic, kenchan is right, OctaneGuy will definatly know the answer to this one, or maybe Heather from detailers paradise, but she is busy with inventory until the end of the week.

 

ugh, no contest

 

PC vs Dremel, might take a lil longer

 

mmmm i asked for a dremel for my birthday and my dad laughed at me. i really have no use for one. o well.

 

FWIW- I've had nothing but success with the Meguiars' (branded) Porter Cable!

 

Sorry for the delay, I didn't see this thread. Aww Thanks Trent!!!

That Northern Tool isn't a Random Orbital polisher--that's a rotary buffer

I think it's crucial that when you are looking for a tool you understand what you are looking for.

The rotary buffer (RB) is a tool for professionals. Its not that a non professional couldn't learn it, but the risk you take on permanently damaging your paint is very high.

With that said, you want a variable speed random orbital polisher. And to date, you only have two choices. The Porter Cable or Griots polisher. The Porter Cable 7424 or 7336 and various numbers around that-- are all the same units.

The Meguiar's G100a is the same polisher with a backing plate, foam pad, and lifetime warranty.

Others that sell the PC like Detailers Paradise offer bundles or the standard unit for all around the same price. HERE

While a lot of people balk at the price of a PC--it will last a lifetime, and will significantly reduce the number of hours waxing and polishing any car you care to work on, and further, if you buy any starter detailing kit--the price of the PC isn't all that much greater than a wax/polish kit that won't last a lifetime!

Like others have recommended, my DVD is hugely popular in the detailing world as it covers hand and machine techniques plus all the necessary things like taping the car, claying, waxing, maintaining, choosing products, etc...
