I have some questions about liquid masking that I'm hoping someone can help me with. I've got a couple of 3 oz jars of Hobbico Master Mask and one 2 oz jar of Parma Liquid Mask. I've recently found out there's another one called Bob Dively Liquid Masking Film, though I haven't yet found a shop in my area that carries it. (So. CA, Pasadena area if anyone knows of a place). Here are my questions:
1) Is any one of these clearly superior to the others, either in useablilty or economy?2) Since they're all water-based latex I figure that they can be airbrushed on provided they're thinned properly and used with the proper tip. I'm using an Aztek A470 dual action and I have all the available tips. What's the recommended thinning ratio and spraying pressure for each and which tip would likely work best?
3) Can the design be drawn directly on the dried mask with either a pen or fine point marker without bleeding through or into the paint being sprayed on?4) If, when cutting a design where two lines come to a point, the cut extends beyond the tip of the point on one or both sides, will the paint bleed through the cut, or does the mask self-seal to some extent. Otherwise, does the cut need to resealed with another light coat of mask?
5) If the mask is self-sealing should the entire design be cut before any paint is sprayed on? Otherwise, it seems the paint would likely hide the other lines to be cut, right? Would the next section to be peeled off need to be recut to avoid lifting the paint just sprayed?5) Any particular tips to applying, cutting or removing liquid mask that anyone can impart to me?
Thanks,
Gary
