CD Test

When doing the CD test to check for towel quality, will a cd scratch easier than paint on a vehicle?



The reason I ask is I just got some new towels (supposedly high quality) and when I went to CD test them, under "harder" pressure they scratched the cd.
 
Generally, yeah, the data-side of a CD is *usually* softer than auto paint. But some paints (e.g., recent BMW blacks) have unusually soft clearcoats and some CDs (CD r/w disks, IIRC) are also *very* soft, so you can only generalize so much...



The amount of pressure can matter, so keep it in mind when using them on paint. Distributing the force over a wider area (fold the towel, don't concentrate force by pressing your fingers through the towel into firm contact with the paint, etc.) will help a bit. This gets back to the "test them how you use them" idea...you want to simulate the actual usage conditions, not just see if there's some way to make marring happen. But you wouldn't want to kid yourself about towels that just aren't soft enough either ;)
