So you`re saying move the polisher even slower than the traditional "one inch per second"??` Would this also apply to the use of polishes???

Pwaug-


`


Try the technique Mr. Theal presented. You will be will be VERY surprised how well it works. ` A good friend and one whom I consider a mentor displayed the same thing to me... it was night and day!


`


I had to change my mindset a little... working with M105/ M100 I would get in one section pass (maybe two at most) and the products were done. `BUT the finish and the removal of defects were both remarkable. I have also experienced less dusting with proper externalities (good weather and good ambient temp.)


`


It`s the ironic saying that applies here... work slower to work faster/ smarter.


`


Regarding polishes/ polishing... my mentor pointed out that the you can work the polishing step faster than the compounding technique being described in this thread...`if you are not `jeweling`. `However, I defer proper polishing technique to other`s more experienced. `


`


The above are just my experiences with the technique Mr. Theal explains in the video.


`


Best regards,

Good video Barry.


`


Abrasive Isolation is a great phrase. I like to view the leading edge of my pad as the starting point and the rear edge as the end point for a products workability. The heavier the corrective product the longer it typically takes as you`ve shown. Once folks start paying attention to how products talk to them as they work them they stop viewing using a machine as a step a, step b, step c process and more of a dynamic process that requires more time the better their results will get.

Great video Barry!`

I would much rather make 1-2 extremely slow arm speed passes over a section then 3, 4 or 5 passes at medium speed. This works excellent and everyone should try it and see 1st hand how well it works. Big thanks to Barry for putting this onto paper/video.`

His movement was about 1"/sec. `Assuming the pass was 18" he took 25 seconds moving to his right and just under 20 seconds on the return. Just slightly slower.


`


`


Barry,`


`


It would seem, theoretically, that moving twice that speed but making double the passes would result in the same amount of abrasion. `Just curious to hear your thoughts. `Does the theory change at all when working with DAT products vs. SMAT?


`


For the record I personally choose to move slowly, ~1"/sec, for three reasons:


`


1. `Better able to see the progress being made by comparing the leading edge to the trailing edge. `Multiple fast passes does not give that contrast.


2. `I tend to get a longer working time from polishes since they are not left in a thin layer on the paint exposed to air to dry out.


3. `Easier to keep the pad flat since I use body movement more than arm movement, the latter of which increases likelihood of tilting.

`


These are very good questions and observations... interested in the reply.

Hasn`t Thomas been saying this for some time??`` I seem to remember Tunch even giving him a hard time because he moved the polisher so slow.

I feel the slower you go, the more concentrated, efficient AND effective the abrasives are able to do their job properly.`


`


I don`t think you can balance out the equation the way you suggested? 1 pass that takes you 30 seconds compared to 15 passes that takes you 2 seconds each will not give you the same results. The abrasives skim across the surface too quickly.`

I think many people have been preaching slow arm speed for a while. Barry is the 1st to actually put this idea in an isolated article` `.`

`


That`s a little extreme on the example but even with that fast of arm speed it is relatively insignificant compared to the speed of the machine.`

`


Yes, he would get "pissed" - he didn`t want to hear my explanation


`


Thank god for Barry Theal, for paving the way.` ` <_<` ` ` ` ` ` `

A bit of topic ...


`


No priming the pad? The pad kinda looked similar to the B&S MF cutting pad.

Nope. WIth the HD polishing compounds you only need a few drops. The lubricants will disperse the abrasives without any issues.`


`


And yes, that`s the exact pad Barry was using. Great pad btw...

david, can you pm me? for some reason i`am unable to pm anybody!
