hi

what hapn to the clear coat its will removed or no?

[Zlyzer]

To be honest, it doesn't make a huge difference whether you use the edge or the flat. I wouldn't fret over it.

nice vid... VERY informative! congrats on a well made video!

CaatingStonez - All good points. This video is a few years old. The techniques Tom uses worked very well for him in his business and on his show cars. Your points however are very good and make sense. I have had many comments from people who use the flat part of the pad with great results. Thanks for your input.

[CastingStonez]

1. Heat is generated at the outer part of the pad more than the center section of the pad. Why? the outer part of the pad is rotating faster than the center? FACT

2. Product gravitates to the center part of the pad? FACT

3. Lack of product of ANY portion of the pad, creates HEAT? FACT

3. Heat generated leads to BURNING paint. FACT

3. Conclusion: Tilting the buffer and using the outer edge which has less product will increase the possibility of BURNING paint. FACT

@CastingStonez

Um, could you please explain your second point to me? Surely, product gravitates to the outside edge of the buff due to centrifical force?? Why would it travel inwards towards the centre? that makes no sense to me!

@PhatArtz

Okay... its like the earth... The earth spins, so why dont we just fly off into outerspace? Gravity. Gravity is the force "inside" a specific area of a spinning object. But, anything outside that area will be thrown out.  With the pad on a buffer, the inside 1/3 of the pad with create a gravity effect and draw product inward. Any product outside that 1/3 or the remaining 2/3 will be thrown out.

Hopefully this helps.

@CastingStonez Hmm, that is very interesting and explains the polish buildup in the centre of the mop. Thanks for the explaination, I learned something :)

agree about diminishing abrasives are out of date but not flat buffing

[PhatArtz]

@svr73 If deminishing abrasives are out of date, how is it done now please?

[svr73]

@PhatArtz Diminishing abrasives have now been replaced with Non Diminishing abrasives and compounds replaced with single polish systems such as Tom's System One X3 (love it) and Xpert polishes (company who initially distributed System One in Australia) but now make their own

There are two types of burning - foam pad burning aka scouring from becoming too dry and delamination from creating too much heat with foam and making the clear coat blister or bubble, like air bubbles on a sticker

[PhatArtz]

@svr73 Wow, that sounds cool, I assume it is a lot faster? Where can I get these products and what do you reccomend? I live in Tassie and the suppliers here just keep selling the same old stuff they always have!!

@PhatArtz PM sent to you

If you're good, you could buff flat or at an angle......it's all in the person with the buffer. Experiment on an extra fender or door.

According to Tom Horvath, flat buffing, particularly with diminishing abrasives is out-of-date.

Buffing on the edge is faster and consistently yields better results, particularly when using a single product system like System One.
