Congrats on the new Tesla Model 3.
In sprayable form, Hyper Polish is the least abrasive polish. I believe Optimum finish might be slightly less aggressive but Hyper Polish is best to use with Optimum coatings as it contains additional product to aid leveling of coating (as do all sprayable Hyper compounds).
The least aggressive Optimum pad is the blue waffle pad which is considered a finishing pad. Typically this very soft pad should only be required for the most finicky (soft) paints which are typically Japanese makes (nissan/infiniti). For most paints, the Optimum black waffle pad is most appropriate for final polish. You can go with other flat polishing pads from other companies (Lake Country or Buff and Shine) but Optimum recommends waffle pads for two reasons:
1. Minimize temperature rise on panel - modern clear coat paint will swell when it gets hot which makes the abrasives in the polish/compound less effective so you want to minimize the temperature rise of panel during polishing/compounding. The waffle pattern allows for more air flow to keep the panel cool. Recommended speed setting on dual action polisher when using Hyper products is 3
2. Minimize stalling on body lines - when using dual action polisher, the rotation is free running and can stall when you hit high points. The waffle pattern minimizes the chance of stalling compared to flat pad. The waffle pattern is also more effective at polishing these indentations without having to change to smaller diameter pad.
I would also recommend you have some Optimum Paint Prep on hand to do the final wipe down. A standard 15% IPA wipe down is adequate but when compared side by side with Paint Prep, it is no contest. When using Paint Prep, I find gloss coat is absorbed almost fully minimizing potential high spots.
