Review: Excellent purchase ! - Absolutely wonderful little masking fluid pen, it makes it so easy to do tiny little dots (for snow fall etc) or anything else you need a fine detail for . Very easy to use , cost effective and with no apparent smell . It's very useful having the blue coloured fluid, it makes it easy to see where you have applied it .. it sticks beautifully to paper just remember to rub it off with your fingers NOT an eraser, or it will make holes or dents in your art work . Flows well , just the right consistency and stays where it's put, all round, excellent purchase !
Review: Great masking fluid that doesn’t pong - I like the fact that this masking fluid can be applied to the page by squeezing the bottle (other types come in a pot and applying it ruins any brush that you use). Also this masking fluid is not smelly, unlike others that stink of ammonia. The only thing to be aware of is that it takes quite a long time to dry, so you need to be patient.

## Features

- 🎨 THE BRAND: Schmincke has been producing the best, finest artists' colours Made in Germany since 1881 and they are available in over 60 countries. The range includes watercolours, acrylics, oil colours, pastels, gouache colours, airbrush colours and much more.
- 🎨 Blue drying, odourless masking fluid for masking areas on watercolour paper, smooth drawing cardboard and similar painting surfaces that are not to be worked on. Apply directly from the dispensing pen with fine tip.
- 🎨 Ammonia-free synthetic resin dispersion. The product is water-miscible, but dries quite quickly to a rubbery, water-insoluble film.
- 🎨 Application: Cover areas of the image that are not to be processed with the dosing tip. Only colour over with water-based stains such as watercolour, gouache or AERO COLOR Professional after complete drying (depending on the layer thickness, a few minutes to one hour). After the colour layer has dried, remove masking fluid by carefully rubbing it off with a dry, grease-free finger. (Do not peel off!)
- 🎨 Please note: The product must not remain on the substrate for longer than 2 days and must be removed completely. Particularly soft, weakly sized papers with structure, such as rag or torchon papers are not suitable for the masking technique. Close immediately after use. The dispensing tip can be cleaned with a needle if necessary.

### ⭐⭐⭐⭐⭐ Ok but not for models.
*by M***O on 25 July 2025*

Great for what it is but not suitable for my purposes. I purchased this to aid in painting plastic models but it grips the plastic surface too strongly and comes off in small pieces. On paper it can off easily enough.
