India Ink vs Acrylic Ink?

[TinyTurner]

I was going to get a selection of colours together to use as weathering washes on structures mostly, when I discovered there are now Acrylic inks available.  It's a technique I would like to try.
What have you found most suitable, India inks or acrylics?     
I guess they are not compatible with each other?

For weathering "washes" I wouldn't use "inks".  I would use artist's oil colors, thinned with artist's Odorless Paint Thinner.

I've been using these for much of my weathering for both diesels and steam engines lately, and I am extremely happy with the results.

The set I bought was on sale at Hobby Lobby and is the "Master's Touch - Fine Art Studio" 20 count set of .7oz (22ml) Tube Oil Paints.

Although I bought 1 quart of "Odorless Paint Thinner" for the convenience of it, regular "paint thinner" works just as well, although it isn't as high quality, but costs considerably less.

For excellent result for only "washes"...y'know...getting into the cracks & fissures...then wiping away what's above that, I highly recommend Tamiya Panel Liner Accent Colors, which are specifically formulated for this kind of weathering/accenting application on models.  It's also an enamel product, and cleans up with paint thinner.  I use it all the time for bringing out tiny details and it's available in several colors.

Instructions for using both artist's oil paints and Tamiya Panel Liner for weathering are readily available on YouTube.

Cheerio!
