What Is the Next Step in Aggressiveness?

[Simon777]

I'm having problems with some water etchings and the most aggressive method I've tried involves a G110 V2 set to 6 with a cutting pad and ultimate compound with 6 passes.

50% of the water etchings dissappear, but I need something even more aggressive to cut deeper. Is there any method I could try besides switching to a rotary that is more aggressive than what I am doing? Perhaps a wool pad and stronger compound?

M105 is more aggressive than Ultimate Compound. Try going to a water spot you haven't worked on yet and use the UC by hand on an individual water spot and see how that works.

I'll give it a try, but isn't working by hand a step down in aggressiveness?

Not necessarily. Working a smaller more concentrated area by hand can be more aggressive. Working a small area by hand allows for more continuous cut on the same area of paint. Even with 4 inch pads, you tend to work a larger area than you typically would by hand. Try working a small 4 sq inch area. Just give it a try and see how it works. It may take them out, or it may not. The only way to tell is to try it.

Well, I tried a couple things you all suggested. First, I used ultimate compound on a new area with untouched defects and it surprised me as it did the same job as using ultimate compound with a cutting pad on a DA. So I guess it does have a good amount of cutting power, but the deeper water etchings still remained.

Next, I worked a smaller area and it did get out more etchings. Rather than getting rid of 50% of the etchings, I now got out 60%.

I'm thinking about trying some M105, but I have some questions. How much of an improvement are we talking here when going from UC up to M105 as far as cutting power is concerned? Is this product alright to use on a DA?

105 can be used with PC As far as the etchings goes, it's hard to say without knowing how much paint you have to work with. Maybe just get it all shiny, and live with the imperfections, unless you want to try your luck wetsanding.

As Fly Bye said, it is pretty hard to tell without doing a test spot and seeing. Sometimes water etching can go very deep to the point where it actually chemically stains the clear a small amount, and it is almost impossible to get the spot completely out.

105 is more aggressive, but before you go out and buy any, have you tried doing two passes over the same area? I don't know why I didn't think of this first, but sometimes another pass, or even a third pass can make a huge impact. If that doesn't work, I would try some M105 and see how it works.

It may be something you may just have to live with if you can't get the faint remains of those marks out, but let us know how it turns out for you.

I had some decent luck getting some water etching out with M105. I did try it with UC first and that didn't do quite so well. I'd say give M105 a shot. Follow it up with M205 for the best results.

If you've used UC with a cutting pad on speed 6 for 6 passes and the water spots are still there, then you may well have a very serious issue and getting more aggressive won't always fix things for you. We've seen water spots that would not come fully out even after repeatedly hitting them with a wool pad on a rotary with a very strong compound - over and over again.

If you become so bound and determined to eradicate these that you concentrate on a small spot by hand and just rub until they're gone, you may very well rub through the clean completely. Yes, even by hand. You would not be the first to do this.

How easily visible are these water spots? Are they throughout the paint? We're just a bit concerned to hear that you've hit them as hard as you have already and they're still there.
