Social media fuels demand for photochromic foam pads that visually signal exhaustion levels. Developed by PolishPro Labs, these pads transition from blue to white when their polishing effectiveness drops below 70%.

TikTok’s #PadGlowChallenge has amassed 280 million views, with detailers showcasing transformation timelapses. Independent tests confirm 95% color change accuracy across pH 8-11 compounds. Safety advocates applaud reduced over-polishing incidents, though some professionals criticize gimmicky marketing.

“It helps beginners avoid burning through clear coats,” states ICA President David McLean. The technology now expands to rotary pad variants, with major retailers reporting 300% sales spikes since March.
