When you have been painting for weeks, and then you end up making a silly mistake, and your canvas gets destroyed. Some of the artists may leave the canvas alone and decide to start the painting afresh others may be inspired to move on amidst the mistake and there those who can turn the mistake into something artistic.
You can rectify your watercolor mistake using the water spray method. It may sound bogus but the only way to ensure that the painting is not destroyed in general to make sure that you cover the rest of the canvas with a masking tape to ensure that there is no right painting that is destroyed.
You may also want to use a pestle if you're not comfortable with the water spray the pestle is mostly used to cover huge areas that have been overworked, and they make the areas appear as if they were freshly done and no much work was done on the part of the painting.
