Rotex and Polishing a Car

In case anyone is interested, I stumbled across a video on YouTube with, I assume Festool, demonstrating the use of a Rotex to polish a car.  Of course, one must sit through the demo for using the Rotex for body work, but that's kinda interesting too.


 
do you have to replace the sponges with every car and every grit of paste? unless the sponges a super cheap that could be expensive.

No, you can use them multiple times, until they're worn. The colour doesn't rub off on another car. But don't count on them to be super cheap. Here they cost 14-18 euro a piece.

Btw, I found an info sheet explaining some of Festool's polishing system, maybe some people find it interesting.

Once you have polished and waxed your car using your Rotex, you may find as I have that subsequently, all you usually have to do is apply another coat of wax every 3 - 6 months, depending on what wax product you use, whether your car is stored in a garage when not in use, and if your daily routine requires that your car sit exposed to the weather.  I live in NE Ohio, and my cars are parked inside at night, but fully exposed to the weather during the days of the regular work week.  I live less than 1/3 mile from two active RR tracks, one on each side of my property.  My cars range from model year 1993 to 2000, and the original paint (Jet Black, Imola Red and Ming Blau) on all remains in excellent condition.  They do have some very slight pock marks in the paint due to acid rain etching while sitting out at my place of work.  But that is only noticed by someone looking critically for it.  Most people think they are rather new vehicles.

Before polishing or waxing a car, I highly recommend using a clay bar to remove most contaminants and to provide a very smooth finish.  It only takes about 30 minutes to do a whole car with a clay bar.  Then you can go straight to the wax unless you have a lot of fine "spider web" scratches (that are best seen in daylight or under fluorescent lamps).  These are usually caused by poor washing practices, e.g. polycotton towels, or commercial car washes with brushes.  If you don't remove these partially embedded contaminants first, you run the risk of dislodging them when using your Rotex and creating additional scratches, or having to use a polish (abrasive) with the Rotex, thereby removing more paint than is needed to achieve a fine finish. 

The foam pads can be reused indefinitely, provided you clean them after use.  I have been using the same 8 inch 3M brand foam pad for more than 10 years, doing 3 to 4 cars two or more times per year.  That is easily accomplished using detergent and water.  If the wax/polish/sealant is oil-based, I sometimes use Murphy's Oil-based Soap for the first washing, and sometimes Simple Green surfactant cleaner, then dishwashing detergent.  Ideally, if you use any abrasive polishes, it is strongly preferred to have a different pad for each abrasive type and grit size.  But most vehicle owners are not going to need many grades of grit, body repair shops will.

Also, I find it best to use a foam pad that is oversized relative to the base pad of the Rotex.  I use 6 inch to 8 inch diameter foam pads on my RO 125.  The oversized foam pads enable use of the edge of the foam pad without risk of damaging the paint, and reaching the portions of door panels under mirrors.

If you have read some of the many posts, especially GOT WAX http://festoolownersgroup.com/festool-tool-reviews/do-you-festool-your-car/ by Drew, the man who makes his living detailing [expensive and exotic] cars and even those of Dan Clark http://festoolownersgroup.com/festool-tools-accessories/what-do-you-recommend-for-ro-150-feq-polishing/msg8173/#msg8173  and others  http://festoolownersgroup.com/index.php?topic=7848.0, I think most of them are making themselves far more work than is necessary for most peoples' eyes.  I'm not talking about those who are preparing for concours d'elegance competitions.  From hand wash with a soft synthetic sponge to waxed [2000 Audi A6] car took me only about 3 hours, and I wasn't hustling myself.  I think the results speak well for themselves considering this is a nearly 10 yr old car with 121,000 miles, driven daily to work where it was parked outside across from the VA hospital which has its own electric and steam generation power plant (read acide rain), and also sat outside more than a year when I was without any garage at home due to remodeling, and I live about 1/4 mile from an active RR track.

Steps I used were:
1) Hand wash car -- cheapo car wash soap in Akron city water.  Unsoftened
2) Dry with microfiber towel.  Towels are washed after each car drying use in ordinary laundry detergent and dried in clothes dryer, sometimes with fabric softener laden towelette tossed in for rest of load.  Hey, a man should not complain when his wife is willing to put up with such dirty cloths tossed into the laundry!
3) Clay bar.  I think this is a most important step.  It only takes about 30 - 40 minutes to do the entire car.  I've used a Griott's Garage clay bar for >10 years and it is still good for a few more times.  Wipe off any surface wetted with lubricant after using clay bar with microfiber or cotton towels.  Lightly so as not to create fine scratches.  I've also been satisfied with Mother's brand clay bar kits.
4) Apply liquid wax or sealant (free of any abrasive polishing agents) using Rotex on slow speed (I set my RO 125 on #2) with 6" diameter "medium firm" foam pad.  I used a Griott's Garage Orange pad which is a bit harder [stiffer] than their Red pad that is designed for waxing.  The harder Orange pad provides a little more polishing action.  I used Griott's Garage Paint Sealant (not the "One Step" type which has some mild abrasives within); on other occasions I have used various liquid waxes (and even paste waxes) with equally good results.  The Paint Sealant seems to hold up better against the winter weather (road salt) and car washing.  Ohio uses a lot of road salt, and our winters are usually very wet and snowy.  There is a reason they call it part of the "rust belt."
5) Wipe off the haze with clean microfiber towels.
6) Admire your shiny vehicle.  Take photos and brag about all the hard work and sophisticated technical knowledge required to achieve a shine equal to or better than on most new cars.  The larger scratches remain, though, as shown in PIC_182.

Total Time ~ 3 hours, including hand washing and waxing surfaces of the normally hidden sides of the door frames.

Note the reflections of other items in my garage.  The paint surface has to be smooth and polished to get good reflected images.  Lighting is dual 8ft fluorescent old magnetic ballast type T12 lamps.    The photos would probably be even better if I had used a tripod to take them.  I simply held the cheapo Brica digital camera.

I tried to load four photos from my gallery into the above post, but only two of them will appear, no matter what revisions I have tried to my post.  I had hoped to show some other closeups and another image of the hood area showing clear reflections of many other objects in my garage.  Sorry!!

I've now sorted that out for you, and all four photos can be seen in your post.

Thanks, Forrest.  I'm puzzled at the error in syntax since all I do is click on the insert image button
then paste the URL address of my chosen photo from within my gallery.

I recently took a couple more photos with the same car outside, freshly washed a few months since I gave it that Rotex treatment.
