Masking fluid and applicators

You can use a ruling pen, a rubber tipped applicator or a soft rubber tipped colour shaper to apply masking fluid. You can also use an old paint brush, depending on the area that needs to be covered but that paintbrush will not be usable for painting again! You can also buy 'masking fineliners' to help with creating finer lines! It is also always a good idea to wash your applicator as soon as you've finished using it, preventing a build up of masking fluid.
