The only purpose and function of pros-aide is to give the paint something to stick to, like a primer coat Paint won't stick directly to latex, but will stick to pros-aide. Pros-aide will stick to latex, meaning you now have a "sticky" surface for the paint to stick to. Pros-aide will not affect the properties of the paint (make it more "flexible"). Nothing will do that. Any type of paint that dries hard or stiff will crack when flexed... no matter what you do to it. An acrylic ink is just that... ink. It's not paint (http://www.wetcanvas.com/forums/showthread.php?t=759251 see post #4). I certainly do not know or understand the chemistry behind it all, but I know that it works. There are basically 4 ways (that I know of, more I'm sure) to apply color to RD-407...
- Apply pros-aide to the raw latex, then apply the color on that. (works because pros-aide sticks to latex, and inks/dyes stick to pros-aide)
- The PAX method
- Mix a pigment with RD-407, thin it to a workable consistency, and apply it to the raw latex. (works because latex sticks to latex)
- Add oil based paints to thinned down (with naphtha) rubber cement and apply to the raw latex. (works because rubber cement sticks to latex)
Of the 3, the oil based paint and thinned rubber cement are probably the most durable because of the type of bond you get between the latex and rubber cement. I've never tried it, but have seen examples, and if it wasn't so toxic I would probably go that route. I'm not interested in all the mixing and thinning involved with using RD-407 as a base for pigment, so I use the pros-aide/ink method. I can tell you I am 100% certain the cheap acrylic paint will not last, I tried every way I could think of to make it work and failed miserably every time. You can certainly mix your pros-aide in with your paint, but it has to be a type of paint or ink that remains flexible. I am no expert here, and I would love to hear from some others, because I am always down to learn more and be corrected if I'm wrong (which happens more often than I like to think lol).
