Rotary Usage

[35TH LE]

I read a handfull of post in this thread and have absorbed a bunch, thank you to all that have contributed. However.. after 7 pages my eyes hurt so I skipped to the last page.



Ive heard the term "pass" used a few times in various threads. When using my PC7424 I use the word "pass" when I refer to completeing a whole section. IE.. "I made a pass with the PC and #80 on a 1/4 size section of the cars hood." or " I did one pass with the #80 and PC to the whole car, I may need to make another pass to the whole car to remove more issues."



I want to make sure the term pass is used with the rotary in the same fashion. I get the feeling that when the word "pass" is used, when speaking of a rotary, it means gliding over a certain section 1 time. For instance "I made one pass on the 2x2 section @ 600rpm to spread, then made 2 passes @ 1200 on the same section."



Do you see what I mean? With the PC a "pass" on a 2x2 section means..... spending 3-5 minutes on that particular 2x2 section, which means I would glide the PC over each square inch MANY times. With a rotary a "pass" means I went over every square inch of that particular 2x2 section ONE time.



Am I correct? Im sorry if that makes no sense... its late.

35th, to me a 'pass' is working over a particular section until the product has broken down, as you suggest a 'pc pass' is, regardless of machine used. I agree everyone should use the same terminology and mean the same thing for consistency of conversations..

I would as it gives you smoother operation, IMHO.

Question about taping, do you guys tape the around the gas cap cover. If so, how do end up polishing it, and other tight spots/narrow areas?

Personally I don't tape that area. For small tight areas I either do it by hand or use a 3inch backing plate and 3 or 4 inch pad.

on a pc or rotary in these cases?

 

[Anthony O.]

By rotary...You can find these at some body shops

I'm too lazy to read this whole thread, just wondering what causes the pad to jump/skip... happens to me sometimes and 99% of that sometimes it's on vertical surfaces... too much product??

Could be that you're over extending your reach so try bringing it in, use a step stool to gain some height and also buff with the pad at a slight angle.

It's not the reach, like I said it happens rarely and on vertical surfaces, don't need any more height...

bingo... That is what I do.

 

[noooorb]

I'm a little confused then. You're supposed to tape up the edges cause the paint is thin in those places, but the gas cover edges do not count?

Anthony, thanks for your informative contribution to this thread, it's definitely one of the top one's! :bow

 

[imported_Ivan Rajic]

I think someone needs to start a "Pics of taping before polishing" thread... it would be interesting to see what everyone does/doesn't tape up and how... maybe it's just late and I'm thinking of weird things good night and good info here

 

[noooorb]

^ I definitely agree

Hey i got a question for you rotary guys. How much time difference is there between polishing out a car with a rotary vs. pc? The pc takes me a long time. Sometimes a REALLY LONG TIME. If you guys are experiencing huge time savings with the rotary, then perhaps it is time for me to step it up.

Cleanup after using rotary, and preparation to avoid huge cleanup, cost time too. Some people feel it is a wash in the end. Is it faster or is it a wash? I don't know as we are talking perceptions, not scientific studies. My current perception is that reaching for Cyclo, and not rotary, brings me biggest time savings. That might be as well due to fact I am absolute rotary noob that creates a mess all around him.

I guess the first thing I would do if I were just starting is chose a good quality fine cut or polish before I even started my new polisher, then chose the right type of foam pad for the application and then.

Man I would reach for a porter cable 7424 it can and will cut and polish
