Hello all!
My idea of a section pass is a cross hatch pattern on a 2x2 section? Please correct me if I'm wrong!
If you're using a Porter Cable or the Porter Cable type of tool, for any major correction work a 2' by 2' area is too large.
I know that's what every expert, website, how-to article and video recommends but if you're trying to remove a lot of swirls and scratches it's faster to work a smaller area because these tools are the least powerful.
Then overlap a little into the previous section when starting a new section.
Here's the thread with the definition written out,
Tips and Techniques for using the PC 7424XP Dual Action Polisher to remove Below Surface Defects
Here's the definition...
The definition of a pass
There are two definitions of the word pass as it relates to machine polishing with any type of machine.
Single Pass
A single pass is just that. It's when you move the polisher from one side of the section you're buffing to the other side of the section you're buffing. That's a single pass.
Section Pass
A section pass is when you move the polisher back and forth, or front to back with enough single overlapping passes to cover the entire section
one time. That's a section pass.
In most cases if you're removing any substantial below surface defects you're going to make 6-8 section passes to the section you’re working before you either feel comfortable you've removed the defects or you're at the end of the
buffing cycle for the product you're using.
Also...
Am I adding more product to the pad for every pass I choose to do?
No. Add product to pad, buff out section. Wipe off residue and inspect. Then either buff again or move onto new section. Shouldn't have to buff again because you should dial in your process by doing a Test Spot first. Don't buff out the entire car until you dial in a process that works.
How To Do a Test Spot
was advised that more product can render the correction in affective in some instances.
That's correct. If you use TOO much product you hyper lubricate the surface and the abrasives will glide instead of cut.
If there seems to be enough product on a section, can I theoretically do about 3-4 passes without adding more product?
Yes. Even more. Like 6 to 8 section passes. Just don't buff to a dry buff.
Wet Buffing Technique
Not to reiterate what I'm asking but I just want everyone who helps understand what I am trying to say.
Thank you for your patience and help!
