LMF - Liquid Masking Film
By Joe Beshar and Bill Stevick

      It’s simply a liquid protective coating which is applied to the area of a model where paint is not to be applied when painting color trim and then easily removed to reveal a perfect edge. Anywhere there is a need for a sharp edge of paint line limits, LMF makes it easy! Usually the average modeler reached for paper or plastic masking tape not knowing about LMF. If the surface is flat, it usually compromise to a sharp edges as ugly bleed under can occur. If there is a tight curve or angle to be masked with conventional tape, the problem of tape crimping occurs. Surface condition such as nicks or cavities can make it almost impossible to avoid bleed under. Some modelers will brush on a clear coat along all the edges as a solution but this does not always work very well.

      In contrast, let’s address Liquid Masking Film. LMF easily masks letters, thin lines and curves. It masks any finish or surface without scratches or damage. It leaves sharp clean paint lines without fuzzy edges. Also, LMF is non-toxic and non-flammable. In fact it can also be used as a protective coating for storage as it will peel off as desired.

      LMF is applied with a brush or it can be sprayed on if desired.

Directions for Application:

1. Practice on an old piece before using it on a new project.
2. Stir thoroughly before use.
3. For best results, apply LMF at full strength-it can be thinned if needed.
4. Apply LMF with a soft brush in parallel strokes. The thicker the better. Avoid feather edges, allow to dry after each coat.
5. Runs and bumps in coatings will not affect results. An area coated too thin will not peel off easily. Do not apply or spray to a feathered edge. Use water to clean equipment before the LMF dries.
6. LMF dries in one to two hours and can be shortened using warm air. Best results are obtained by drying over night.
7. Trim design may be drawn on LMF with ballpoint pen.
8. Score design with a new sharp X-acto knife and peel off areas to be painted.
9. Apply paint, allow drying then peeling off remaining LMF. If LMF was applied too thin, use soap and water to soften so it can be rolled off with fingers.

Final Details:

      The difference between a show stopping airplane model and just another model is the final detailing. Scale models are demanding in this area. It is said that you never finish a scale model you just stop detailing it and say "It is done." The true reward comes at the field when a crowd gathers around your model and the people start telling you how nice it looks. LMF can make fine detailing easier.
