thought I would try out a liquid mask for the first time. The instructions say to not paint on a surface that you want to remain clear as it may fog the finish....test on a piece of lexan first. mmmmm....... this was listed in one of those "items that others have bought lists" when you choose a model. If its not for clear styrene, I wonder why others would buy it when buying a model.....
anyone use this stuff? ok for clear styrene? did I blow off $4.00?
thx - Craig
I've tried Parma mask, but unfortunately don't remember the results (poor scientwist I am, I didn't record data). After reading your post I ran down and put a dab on a canopy I coated with Future a couple months ago (guaranteed to be cured), and I'll let you know. I don't remember why I decided not to use the Parma, but I do remember there were no fogging issues if that helps. I also have Microscale mask and Ambroid liquid mask. The Microscale was very runny and didn't adhere well. I let it dry for a couple days, and it had popped itself loose. The Ambroid is essentialy ammonia and latex, and plays hell with acrylic paint (or Future). It adheres almost too well. In a thin coat it's a bear to remove (shreds easily). Thicker coats are hard to apply neatly, but you'd have more there to make it easier to peel/ rub off.
Well, I use Elmer's Glue with good effect. :-)

The Elmer's Glue not only doesn't fog the clear plastic, it removes any mold release from it, and leaves it sparkling like a diamond. A bit of heating with a blow dryer makes it easy to remove by giving it flexibility. The tip of a toothpick can then be used to pry the edge up to let you grasp it and peel it off. If a type of paint is to be used that may affect the plastic, it is best to apply two or three coats and let it dry thoroughly before painting the model. Such a thick coating is also very easy to remove without shredding it. If it beads up on the transparent plastic, a drop of dishwashing soap added to the mixture will make it adhere better. (a trick that also allows a water-based paint wash to be used over a oil-based paint.)

Its targeted for the R/C Car and Truck crowd, most all with vacuformed clear lexan bodies. Its ok for that application, but most preferred to tape off windows or two tone color areas. IIRC its vinyl based with ammonia, not the best for clear styrene, or some paints even.
About the best use for scale models, is if you use templates, paint the blue mask on the back side, press/hold the template to the model till the paper template is 'glued' on. Airbrush away, then peel off the template, and most of the mask comes with.
reduces the amount of overspray that may creep under otherwise. better than frisket,IMO.
