I don't know if anyone is interested....
I was searching through some old art materials, I'm talkin real old, and came across a tub of junk called 'BINDEX'. I was looking for acrylic medium and found this. I can't for the life of me remember why I have it but I do and it's gotta be 15 years old.
It's the consistency of sour cream, a little translucent and smells like artist acrylic paints. The only label description is 'flexible binder'. I'm assuming it's basically art paint minus the pigment and plasticizer (or plus plasticizer, I can't remember which way they work, Gip here's one for you!).
I sprayed a light coat of Future and washed the roadwheels using tube watercolors. If you're not familiar with my posts I try to stay away from anything with organic solvents, period. I have two small kids and have had a serious overexposure to chemicals in the past (that's the reason for the 25 year hiatus from modeling) so it's not worth it for me. I don't know if an oil wash will affect this method.
I took the leftover watery color and eyeballed a 50/50 mix with a scoop of Bindex.
Into that fluid paste went some ground chalk and dry pastel. I stipled it on with a flat brush in small areas (2 or 3 wheels) so it stays wet, and used the tip of an exacto, to flick the material off the end of a few pastel pencils leaving different size and color bits. I then ran the motor to make sure there was no interference and moved on.
The stuff is really tenacious, you can't even scrap it off and it dries clear and matte. I was planning on hitting it with clear coat with the rest of the model but I don't think it's necessary. If I find the acryl medium I'll compare the two if Bindex isn't readily available.
I was thinking about adding more to the inner wheels but maybe I'll hold off based on your comments. I tested a small section of tread first, letting it dry over the drive sprocket to see if it wanted to hold it's shape and it was fine. I guess the big test will be tommorrow to see if it moves after coating the full length. It may be a static model after all.
Thanks
