I thought I made that clear in those videos.
Both choices have their downfall but the first suggestion does NOT create paint damage. If you allow the car to air dry, the drops of water remaining on the car will collect dust and dirt. Although not desirable, that dust and dirt will NOT cause scratches
unless you remove them improperly. If you leave them alone, they won't do a thing but make the car look a little dirty.
If you dry the car with a towel,
you are grinding the dirt that remained on the car after the touchless wash INTO the paint. That's what I call, "making sandpaper". You already know what sandpaper does to your paint so there is no question as to if you should do that or not. I discussed that in those two videos.
Everything I preach is based on one thing: common sense. No rocket science, no Sprint math or calculus 4. It's the simple advice that your grandma would have given you. Some companies like to make this stuff seam like you need a degree is washology to understand it but trust me, I could teach a 8-year old this stuff.
