Rotary ? about product breakdown?

Anal1 · 05-31-08, 07:06

When you say for instance 3 passes? Does this mean to one side and back = 1 pass or is that considered 2? I think I may be working product too long sometimes. What is a usual average # of passes. I know it varies but if you could give a product example and how many passes that would probably be helpful.

I think one pass refers to one application of a product untill it has been broken down properly.

O.K. I see what you mean.

So even with the rotary it is normal to have to go over a panel more than once? That is the problem I am having at the moment. Can't seem to get the RIDS out to suit me. Using System1 with the wool and can't seem to make myself happy. Got rid of the swirls and stuff but not perfection.

Much easier to simply time your polishing. On one panel, I will polish anywhere from one to two minutes depending on what polish and pad combination.

Your going to need another step after using wool......

A finishing polish with a finishing foam pad will bring out the shine.....

On some corrections you can go over a panel quite a few times even with the harshest compounds and twisted wool pads (heh heh, just ask ebpcivicsi about a certain Denali XL, which I recently *re-hammered* in places with the rotary/wool combo...and those RIDS are *still* there).

But when you're doing repeated passes like that, you really oughta use an ETG to check the reduction in clearcoat and also you need to ask yourself if your expectations are realistic. I deliberately leave quite a bit of isolated residual marring in my vehicles as I want the OE paint to last for a long, long time.

"Perfection" is, IMO, mighty unrealistic in most cases; stuff happens and 0.003" isn't much over the life of a vehicle. Two of my garage queens, each with under 20K miles, have RIDS I'd never fully correct...just too deep.

I played around trying to get some panels of my 75K mile M3 perfect, and I overthinned the clear (to the point that it'll be getting painted) *before* I got all the RIDS out. They weren't all that bad looking either, nothing like the stuff I see people here eliminating all the time. Makes me wonder how some of those "perfectly corrected" cars are gonna look in eight or ten years (or even sooner).

I guess my definition of a "pass" is a bit different. Let's say you have a 1.5 X 1.5 area you're going to polish. Moving the buffer head all the way through that area one time is a "pass". Moving the buffer head through the area numerous times until the polish is broken down and ready for removal is one "application." So one "application" consists of the total number of "passes" required to break the product down to the point where it's ready to be removed.

SuperBee364- Heh heh, and therein lies the source of the confusion; which definition of "pass" does a person mean

Both make *perfect* sense IMO, so it sorta becomes a personal preference coin-toss (and you and I are on opposite sides of this particular coin, if only oughta habit on my part).

bwalker25 · 06-01-08, 08:43

I was thinking along the lines as a pass = 1 application, but now after reading this I guess superbee it makes more since that way.

so for me now 1 application = x passes for polish break down....

This is how I generally think of it also. Unfortunately there is not much uniformity in detailing jargon.

Yes I do know to go another step after wool. Thx. And i'm just glad I wasn't the only one not sure about a PASS!!
