Questions about the PC 7424 and upgrade?

Now that business is picking up a bit I am having questions about wether the PC will work for having to do several cars a day?



1) I find that the PC can not remove scratches...is it that I am not using enough cutting power or the right pad?



2) The PC is time consuming when it comes to needing to buff a car and put down wax in an hour or two. Are there any tips I can use to quicken the pace with the PC? What can I do to buff off the wax besides doing it by hand? Will I have to switch pads on the PC continually to do this?



3) Most people I run into that do detailing have the DeWalt DW849, is this a tool I need in my arsenal?



4) Those of you that actually detail what are you using and how do you keep the time to do a detail down? I detailed a BMW 528 that was in good condition tonight and it took me 5 hours? I may have process issues? I do the interior first which took me like 3 hours.

I just got my PC and found that the stock screw in pad works great on a MF towel set on 2 to buff off wax. I have used it on #26/Glanz/ #9. I got 10 Wal-Mart M/F towels ( CD test passed) for this. 2 will do a car, gives in essence 8 surfaces. Buff the majority of #26 off a sedan in just minutes leaving the hand work to the small areas.



A while back I bought a cordless Simoniz R/O buffer thinking it might do for me and now that I bought the 7424 I found that it with its 4" pads work great for applying paste or liquid wax ( not Z or SG ) and I can put paste #26 evenly and thin on a full sized sedan in 10 min.

Qs1&3- There are some types of marring that can only be (properly) removed with a rotary like the Dewalt (or the ever-popular Makita). Using cutting pads and stronger abrasives with a PC will only go so far, and will sometimes cause abrasive-induced marring that won't quite polish out. But you'd better set aside a LOT of time with junk panels/beater cars to practice on with the rotary. It's SOOO easy to make a mistake and damage the vehicle. Imagine having to tell a customer that a) you damaged the vehicle, b) they'll have to have a panel repainted because of you. Better give this a LOT of thought.



Q2- Polishing with a PC *CAN* take forever...just the nature of the beast. For waxes and sealants, I get good results applying with the PC and removing with MF bonnets. I sometimes have to go over it quickly by hand too (to get the final 5% off), but the bonnets cut the time down. Recently, I removed all the (3M Showcar Paste) wax on Accumulatorette's A8 with only one Meg's MF bonnet, and didn't have to go over it by hand at all. I put it on with the PC too, didn't take long at all (and I generally work sorta slowly).



Q4- Can't help ya here, I'm slow. I honestly don't know how anyone can do a car, meticulously, in a short period of time...when I was doing it professionally, I didn't/couldn't do the same level of work I do on MY cars, it would've just taken too long and I always had a certain number of cars that had to get done :nixweiss
 
I undertand your issues, I use the PC too, and spend a lot of times on the vehicles, between 5 and 6 hours each car, but I think is better to take the time and use the PC than the risk of using a Rotary, and on the other side, I always tell the customers that the paint of the car is like skin, you better treat it with patiente and soft things, and I better explain to the customers that some deep scratches are better to live with them than taking them out. unless you want to repaint the car
 
You can get bonnets at Top of the Line or I think Classic Motoring Accessories. TOP I know has em for sure
