Kevin Brown Method: Priming your pad depending on the goal

<p>According to Kevin Brown there are different kind of ways to prime your pad&period; For defect removal we use a different approach in priming the pad than for final polishing&period;<&sol;p>&NewLine;<h2>Pad priming for defect removal<&sol;h2>&NewLine;<p>A pad should best be manually primed&comma; because we don’t know in which way the strands are bending or twist&period; While priming&comma; the hole face of the pad has to be covered with buffing liquid without any accumulations present&period; For defect removal&comma; pad priming will give the following benefits&colon;<&sol;p>&NewLine;<ul>&NewLine;<li>It increases the useable surface area of the pad&period; When filling the pores with liquid&comma; this creates more surface area to put buffing liquid on&period; Which increases the effective surface area of the pad&period;<&sol;li>&NewLine;<li>It mass-loads the face of the pad&period; Keeping the pad free of saturation allows the pad to compress and rebound as it was intended&period;<&sol;li>&NewLine;<li>It stiffens the face of the pad&period; By priming the face of the pad we make the walls more stiffer&comma; but they will deflect in some way&period; This may come in handy if you work on a complex shaped panel&period;<&sol;li>&NewLine;<&sol;ul>&NewLine;<p>Defect removal is probably not the only purpose of your polishing session&period; Besides priming your pad for defect removal&comma; there is also a different approach which is a priming a pad for final polishing&period; The priming for final polishing is a bit different&period;<&sol;p>&NewLine;<h2>Pad priming for final polishing<&sol;h2>&NewLine;<p>For final polishing&comma; thorough priming of the pad is useful&comma; but excessive amounts of polish should be removed before buffing&period; This is done by blowing the pad clean using compressed air&period; Or by placing the pad on a microfiber towel and turn the machine on for 3-7 seconds&period; It seems wasteful&comma; but consistency in coverage of the pad is necessary&period; We want the hole surface area that is available&comma; to do its work with the same amount of liquid&period; Moreover the abrasive grains in liquid nowadays would probably fail to disperse in an even manner&period; At some point in the polishing session most of the abrasive grains become trapped in the pore structure of the pad&comma; attach to the paint surface or float away from the polishing area&period;<&sol;p>&NewLine;<p>The abrasive grains will move across the paint by the pad in the followings possible ways&colon;<&sol;p>&NewLine;<ul>&NewLine;<li>Through encapsulating the liquid within the pore structure&period; We assume that no grains are in contact with the wall-tops&period;<&sol;li>&NewLine;<li>By shifting and tumbling the abrasive grains that are between the paint surface and the pad&period; The wall-tops move the grains over imperfections in the paint surface&period;<&sol;li>&NewLine;<li>The grains are attached to the wall-tops&period; In this case levelling ability increases&comma; because the grains and the pad are moving in the same way&period;<&sol;li>&NewLine;<&sol;ul>&NewLine;<p>The polishing result will be negatively be influenced&comma; if there are no free-rolling grains present on the paint surface&period; The abrasive grains must be forced into the defects via downward pressure&period;<&sol;p>&NewLine;<h2>Misconceptions<&sol;h2>&NewLine;<p>There are some misconceptions on abrasive particles&semi; the opinion is that when they attach to the face of the pad&comma; the polish breaks down quickly and the lubrication evaporates fast&period; But working at a high speed causes a lot of paint to be removed&comma; so it is not that odd that the grains can’t do their job after a short period of time&comma; because the liquid is covered with paint residue accumulations&period;<&sol;p>&NewLine;<h2>Priming your pad with the Kevin Brown Method<&sol;h2>&NewLine;<p>In the Kevin Brown Method a microfiber pad is primed with defect removal as goal&period; In this procedure the pad is primed with a massive amount of finishing polish&period; You have to massage the liquid into the pad so that it covers the whole face of the pad&period; String saturation has to be reached without accumulations&period; The Kevin Brown Method also &OpenCurlyDoubleQuote;primes” the surface area of the paint&period; The result is an increase in the effective surface area of the pad that is in contact with the surface of the paint&period;<&sol;p>&NewLine;
