Can the old traditional cardigan be colored without transition?

The paint surface cannot be painted with acrylic paint. They have different chemical properties, are incompatible with oil and water, and will separate the shell.

I always paint on the surface with oil paints, which will never fade.

When acrylic pigment is applied to paint, it will become brittle and fall off because of its water solubility. When the paint is mixed with oil, these problems will not occur.

But it's not best to keep it dry after painting, because it dries slowly, and it's not best to keep the amount of dust around it, otherwise there will be too much dust on the surface after drying, which will make the painting dirty.
