I know that, it's just that it takes a lot of time. Also you don't need the wireframe mode, just use the wireframe overlay. But my model has a lot of floating geometry which keeps intersecting with parts of the main mesh. Thankfully I found a couple of good tutorials and learned about the weight transfer operator which should make my life much easier. And it's good to know that you're supposed to use Auto Normalize in your brush options.

But you can't really make good gradients in edit mode. Although it's good to quickly assign geometry to bones with a 100% weight.
