Why is the water blade never discussed?

I've been using the CWB for a couple months now & am fairly happy with it overall. I usually wipe off the blade every other pass with a clean MF rag. If you're concerned about marring the paint, just use it on windows. It works GREAT on glass!
 
I think you have just as much of a chance causing a scratch with this as you do with a WW. WW's can pick up many things if they touch the ground or anything else.

Autopians know not to let any detailing tools touch the ground especially WW's. Those that do get tossed in the wash and not used again during that session.



I would NEVER use a CWB on my car or anyone else's that I might be detailing.
 
So how, or more specifically where, on the water blade would a piece of debris get caught to the point that it'll stay in one spot and drag the whole length of the car?

We are only talking about a mm of surface area that is in contact with the car.
 
Accumulator had it right. It works good until you get a some marring then you will never use a water blade again.



To make sure that I never instill a mark on my vehicle with a water blade I gave mine away. There are only two types of water blade users. Those that have intilled scratches or marring and those that will eventually instill marring and scratches.

It might not get stuck between the blade and the paint but it could drag the dirt over the surface. It doesn't take much on some soft paints to mar.
 
I think this is a classic example of "flocking". Some people have had bad luck with them, so everyone assumes they can cause bad things. You have the exact same chance (even more) to cause harm with a towel as you do with this.

You think you have more of a chance to mar with a towel? A proper Waffle Weave Towel shouldn't be causing any marring at all, especially if you are dabbing the water to soak it up and not dragging it all over the surface.
 
Same with this device. It is all about if you happen to pick something up with it. More surface area of a towel means more of a chance to pick something up.
 
I used few time when I didnt know about Autopia yet.

I currently using CWB for my bath cermanic tiles(weekend cores).

But a towel will pull the dirt away from the paint not smash it into the paint.
 
That is not true. While you are drying, you are not constantly pulling away. Plus your chances of picking something up, are 1000 times more due to surface area.

You are not constantly pulling away but the towel will pull water and small dirt particles away from the surface. And surface area doesn't come into play like you are thinking. Sure the towel is bigger and the towel has more surface area but you are covering the SAME amount of surface. If you dry and car with a 20 foot by 20 foot towel you have 400 square foot of towel but the surface area of the car stays the same.
 
True, however it is the surface area of the towel that could pick something up. From the air, the ground, the car, or anything else.

If you have dirt flying around in the air you are washing your car in a bad spot. ;)



If you drop your towel on the ground or it touches the ground you should be using another clean towel.



I really don't see a towel picking up any particles from anywhere other than the car.
 
Dirt and dust is in the air everywhere whether you believe so or not, unless you are in a paint shop. 2nd, if you ARE correct, then why would the blade pick anything up either?
 
Even with light pressure and a very clean water blade, we noticed slight marring on my partners black CTS. We stopped using it. Only time it comes into play now is to remove water from windows after washing, or to remove dew from my daily driver before I go to work in the morning.

The blade isn't going to pick anything up. Like I explained it will drag the particles on the paint surface across the paint. the towel would pull the small particles AWAY from the paint. Also, when using a towel most people fold it and use several sides of the towel so if there was anything on it would not be dragged across the car for the entire drying process.
 
People are missing the point. My point is that the same marring can come from a towel. No pressure at all is needed with the blade.
