When removed, it also removes the first layer of paper. The bad smell is expected. Also, someone said it's yellow that's why they returned it. IT LITERALLY SAYS ON THE DESCRIPTION THAT THE COLOR IS YELLOW. So fix your expectations.

It has a fishy smell,,also came yellow color

My grand daughter was very Happy with this.

Goes on easily and rubs off just as well. Performs as expected, very nicely covering areas to remain white in watercolor painting. Dries quickly.

Me gustó porque su capa es más gruesa que otros productos y más fácil de quitar

This fluid is good for blocking out small areas we want to remain white when painting watercolours. I often use it for the highlight in the eyes. I often apply it the night before I start the painting so it has a long time to dry. I use a wooden stick or tracing stick to apply the masking fluid as it can damage brushes. A dip pen also works okay, but can scratch the paper if I'm not careful. If we need a bigger area left white then it's better to just not paint that area or use masking tape cut to shape. This masking fluid is mostly for small areas. It seems to be best if removed within 2 days of applying and even then, be careful as it can tear the paper. Best to test before doing an important painting. I made the mistake of shaking it vigorously at the start and this introduced air into the mix which caused some clumps. It's much better if I stir before use instead of shake. This is user error and not a problem with the product. Basically, it behaves exactly as I expected and would be good for watercolour artists of all skill levels.

Very easy to apply - works as I expected.
