The most common way is to lather a brush up with soap and then dip it into the fluid and paint with it. Sometimes your brush is toast afterwards.

There are tools with thin needles to apply it but they can clog up.

Here are masking tool pens that disburse a fine line of fluid. Keep clean.

I like to use the end of a pointed brush. You can make very fine lines and then just wash off the brush end. (see video)

I’ve found out and made a new applicator I call a masking wheel (see second video) This is great for unusual shapes especially in water.

For large areas use can use Frisket or contact paper and cut out your image to be preserved and apply it to your surface

What of masking fluids are there?

I prefer Pebeo Drawing Gum. It’s relatively thin and works beautifully for me. It’s a blue color.

There are lots of other masking fluids on the market and they are in different colors from white to yellow to blue.

How do you take off the masking fluid?

• You can rub it with your finger
• Use a pick up tool (see video)
• You can use masking tape to grab it and pick it up (see video)
