Stumbled upon this on accident and it really helps, best success I've had so far. For anyone looking to remove or edit their weathering.
Things you will need:
1. Thick Dry Erase marker
2. Paper Towels
3.Windex
Simply dry erase over any spots you want removed, let dry for 15-30 mins. Get a paper towel wet with windex and wipe away. It will pull the marker off and a good amount of the paint. Repeat as necessary.
This is the best method I have found, eliminates hard scrubbing and won't damage armor. And this really helps on giving a visual on what is going to be removed.
