What paint from your range is the best to use for tinting?
If you want to tint the paint yourself, it is wise to use a product with a lower whiteness. It is not worth buying a super white coat when you tone it with liquid colours. From our product offer we would recommend PRIMALEX Project. You can also try PRIMALEX Optimal, however, this paint is brightly white.
However, remember that mixing the same shade for subsequent repair is not easy. Use PPG Color Center just to be safe.
