Welcome to AutogeekOnline... :welcome:
Hi all, I'm new to the forum (I'll get pics and all that good stuff up eventually) but I want to know more about the Porter Cable 7335 polisher.
You see, my dad's friend got it like 10 years ago with some kit he won or bought, and he recently gave it to me. It also has a Meguiar's logo on it, if that makes any difference.
Back in the late 1980's or early 1990's Meguiar's introduced the Porter Cable to the car detailing world as at the time, they were the only company that I know of that actually made a foam pad that fit this tool. I document that here,
The history behind polishing paint with a DA Polisher
Does anyone know the history behind where these paint polishers came from?
Well here you go...
In the below picture is a new, never before used
W-6000 6" Dual Action Buffing Pad from the late 90's, these were around back to the 1980's and possibly longer, I don't know it's hard to find anyone
alive that remembers that you can
talk to.
Note the wording states you can turn any dual action sander into a dual action polisher...
For those that might not know, this is an air powered, DA Sander, commonly used on body shops to sand paint, primer and bondo. ALL body shops have these air powered DUAL ACTION sanders that use a 5/16 spindle to hold a backing plate.
The W-6000 has a 5/16" threaded stud affixed to the plastic backing plate...
Here it is attached...
Here it is hooked up to an air line...
And here I am running the DA Sander/Polisher over the trunk lid of a Honda...
Then sometime in the late 1980's or early 1990's someone discovered that the pad Meguiar's sold for air powered DA Sanders would
fit and work on a Porter Cable DA Sander.
Note when I typed,
fit and
work, that's two things, there are lots of electric DA Sanders, but most won't power a foam pad, only a thin sanding disc.
And there you go... Meguiar's, a company already selling and teaching people in the body shop industry how to finish out swirl-free on fresh paint after first using a rotary buffer introduced the same pad to the enthusiast or consumer world using a tool that the average person can plug into an electrical outlet in their garage.
The average person doesn't own an air compressor large enough to power an air powered DA Sander as a polisher around an entire car. See my article below...
Then somewhere along the line Porter Cable included a copy of the Meguiar's W-6000 DA Pad in the box and called their DA Wood Sander a DA Polisher.
Try to find that little tidbit of paint polishing history on any other detailing discussion forum.
I have plenty of experience using Random Orbital polishers (Dewalt, I forget the model no.) to spread waxes while working in my dad's shop detailing cars. The Porter Cable 7335 is labeled as a Random Orbital polisher, but I want to know if it can be used for paint correction like a DA polisher such as the PC 7424XP.
The answer is yes.
The Porter Cable 7424XP is the latest version of the 7336 you have. It has more power or at least seems to be better able to maintain pad rotation when doing correction work.
I really want to know if there is a difference between a DA polisher and an RO polisher, as well. I've gotten mixed answers thus far in searching, so I thought I'd ask the question myself. Thanks
Don't get hung up on terms used to describe a tool that will both rotate a pad and oscillate a pad at the same time and this is what the 7336 and the newer 7424XP will do.
Here's an article I wrote to help you get the best use out of your first generation Porter Cable...
How to MAXIMIZE your DA Polisher
You want to start by getting a 5" backing plate and 5.5" pads. Take my word for it... (or not).
