My grand daughter was very Happy with this.

Good tool for watercolors.

Does what it should!

If you are a guoache painter this is a life saver. Adding just a few drops of this to your paint will keep it staying wet while painting. And if you are like me and tend to forget to moisten your paint, this will save you. It does let the pain dry full and keep it wet longer. It does not affect the formula, color, or consitency of the paint. Just add a few drops depending on the amount of paint you squeezed out of the tube, give a good thourough mix and happy painting.

The media could not be loaded. I’ve used this masking fluid for years, and it has never let me down. Recently, I tried switching to a different brand but eventually went back to this one because it works perfectly for me. After drying, it doesn’t let water through, and I don’t have much trouble removing it. Just keep in mind that it has a strong smell, though not overwhelming.Here are some tips I’ve learned over time, if it helps anyone:- The best way to apply this or any masking fluid is with a silicone tip. It’s soft and allows you to spread the fluid evenly. Using brushes can damage their bristles, but if you choose to use one, select an old brush or one you don’t mind getting stained. Be sure to wash it immediately after applying the fluid to prevent it from drying on the bristles.- Since this masking fluid has a beige-yellowish tint, the longer you leave it on, the more it can stain the paper.- It can be removed relatively easily with your fingers or a curved tool that won’t damage the paper. Always be very careful, especially with 100% cotton paper, as it’s more delicate (and expensive!). It’s a good idea to test the masking fluid on a separate piece of paper before applying it to your final work.

Daughter is using at school in an art class, she says it's perfect and at a great price.
