Great article Mike (Smack)!
I had the chance to 'put my hands on this treasure' some time ago, when I had the pleasure to met Smack.
I was mainly a SMAT user because DAT was giving me less than desired results, and other concerns like gummed product difficult to remove, too much dust. Also, I was experiencing PILLING like described above.
SMAT is (IMO) easier for a beginner, see the fact UC is OTC product and used worldwide by amateurs and professionals. For SMAT, I believe a constant pressure buffing cycle is more important since you always deal with same size abrasives, and you can stop anytime. For DAT, you have to polish through the end of a cycle, or you'll get less than desired results.
But the abrasives 'Diminish'/change during your work, so tweaking/changing technique on the fly is likely obligatory in this case.
After being 'educated' with the 'Smack Technique', I've switched to ~90% DAT only user.
I've done some adaptations to my taste, like using higher speed (5-6) on first passes (medium-high pressure), speed 4-5 on 2 more passes (same pressure), and speed 3-4 (now reduced pressure) on last passes to finish down.
I believe Hybrid Pads helps this technique to be flawless, since the Orange Cutting pad works awesome on cutting, but gives you the same 'feeling' of a finishing pad when running slow and with less pressure. The DAT gives you a product to be worked for Cutting while starting, and for finishing on the end of your buffing cycle.
The result of using Smack's Technique is that when I finish a section, I have only a thin film of product that's a breeze to remove.
Thanks 'Smike' for sharing your knowledge with us, I can credit mostly of my recent results to you and your technique.
Kind Regards.
