Hi, I have seen several examples of people doing damp sanding but am interested in tips on how to do this.
Here is my understanding so far. When you are sanding with an electrical DA, you can't do the traditional wet sanding because water and electricity don't mix.
An article I saw by 3M said it is damp sanding when you spray the sanding disk to moisten it, and when you are sanding along a vertical panel there should not be enough water for the water to drip down the side of the car.
This is the part of the process I am interested in, mainly, how much spraying is required, how often you do it or know when to spray, how wet you get the sanding disk, do you soak the sanding disk first, that kind of thing.
If I were to do it, I would probably not use less than 2000 grit, possibly only 3000 and 4000, either using Meguiars Unigrit or Mirka Abralon or both, because this is factory paint/clear.
Thanks!
