Hey folks. I’m not an armor builder but I came across this when I was making something for one of my aircraft builds. I needed to put a tint on a piece of clear plastic so I mixed some India Black ink with Future.
I let the unused portion sit on the counter for about an hour and the Future had begun to congeal. I stirred it up a little and it looked like oil or some kind of sludge. It was very gooey and sticky but it looked good. After a few more hours it dried hard and glossy.
I don’t know how well it would work but I just though you armor freaks might find this useful…assuming you didn’t already know about it.

Never tried that one, thanks for the tip Fly-n
Just remember one thing…scale effect. Applying a liquid that is 1:1 to represent something that is in scale a fraction of the depth might make it look very unrealistic once applied.
Oil is typically displayed in modeling as nothing more than a stain to give the illusion of liquid.
You might find that you have a puddle that is a foot deep in scale versus the 1/4 inch it really would be in actual depth. Convert that 1/4 inch down to 1:35, 1:48 or 1:72 scale and you have in essence something that can’t actually be replicated accurately, so we opt to use a stain instead of the pool of liquid.
Could definitely see this being a way to produce a neat effect for perhaps a dio setting in a repair shop for example or something similar. I agree it would be difficult to use for a simple small oil stain on an engine deck but it’s still a neat tip and something to file away for future potential use. [B]
