钢丝刷本身材质是钢丝，有一定的硬度和强度，可以把核桃的表面刮掉一层。所以圈哥建议打底时如果用钢丝刷，最好轻轻的，不要用太大的力气。不然会把核桃身上弄出好多细心的沟痕来。用钢丝刷打底最适合的核桃就是那些修理过的文玩核桃。用钢丝刷打底等于把文玩核桃的表面全部修了一遍。使修过的文玩核桃上色包浆更均匀。因为文玩核桃修过的地方比不修的地方上色包浆会快些。介于这种原因，我认为修过的核桃用钢丝刷打底效果强于纳米刷。打底时间有3到5天就行了。千万别时间过长，更不能用大力度。
The wire brush itself is made of steel wire, which has a certain hardness and strength, and can scrape a layer off the surface of walnut. So circle brother suggests that if you use a wire brush, it's better to use it gently, and don't use too much force. Otherwise, it will make a lot of careful furrow marks on the walnut body. The most suitable walnut with wire brush is the repaired walnut. With a wire brush, the surface of the walnut is repaired once. It can make the color coating of the repaired walnut more uniform. Because wenplay walnut repair place than not repair the place color coating will be faster. For this reason, I think that the effect of repairing walnut with steel wire brush is better than that of nano brush. It takes three to five days to make a base. Don't spend too much time, let alone use great force.
