Heheh, I've seen this video like a dozen times. His English is hilarious
If you mean the difference between filters and the new Ammo Shaders, yes, but it's hard to explain. A filter is a very soft enamel which is designed not to pool, and is used like a filter in photography (hence the name). It's largely transparent and is normally applied with a flat brush in big strokes, but without pooling. I used this in all my Dunkelgrau (German Grey) tanks, with a blue filter - worked great. The Shaders can be used to achieve the same effect, but they cannot be removed and there is some risk of creating streaks, which wouldn't happen with the enamel filters.
Does that make sense?
