DA over use & Rotary misinformation

DA causes too alot heat cycle with this new gen of detailers chasing rids, and working single panel substrates for 2-4 hrs. Best to learn to sand and rotary techniques= why less stress and heat…. then 3 steps of Da. Which can be done in 45mins-1hr with those steps. I’ve seen 5 vehicles now these past 2 years with delamination on a brand new vehicle from to much heat and misuse with a DA polishing work. When this happens and you causes too much heat from hitting a single substrate panel, you’ll break the base layer coat of the paint off and away from the primer. Which causes rapid Oxidation. Sometimes days to weeks to clearly see it and sometimes months. If your scared of rotary work to cut, learn it. You can sand, rotary, 3 steps da on a Black GM 2500 in less time if not half the time if your chasing perfection learning Colorsanding/Color. Correction vs just using a DA. 2 let the Paint set back down before proceeding with any polishing. Why it’s best to finish polish and coat a car 12-24 after cutting when doing Color Correction. It’s why you see scratches/Rids/etching hours later or next day on a substrate that you knew wasn’t there before because of Heat Cycle.

When paint delaminates or strikes through from heat damage, its chemical structure is permanently altered. The paint will rapidly degrade, flake, and rust. [1, 2, 3, 4]

Immediate Changes

• Loss of UV Protection: Clear coat contains UV blockers. When it or the base coat breaks away, the unprotected lower layers face direct sunlight. [1, 2, 3]

• Porosity Increases: Overheated paint becomes brittle and porous. It acts like a sponge, absorbing water, road salt, and environmental acids. [1, 2]

Future Paint Failure

• Rapid Oxidation: Yes, it causes extreme premature oxidation. Without the clear coat shield, UV rays quickly break down the chemical bonds of the exposed base coat or primer, turning it chalky, dull, and white. [1, 2]
