Hi IronFett
Got some latex

I got fluorescent orenge as it won't get lost on any of the colours I'd use. I figured it would be harder to try and get the edges right if the latex was too close in colour to paint job I was working on.
When you say light dustings, is this in terms of spray speed (i.e lightly pressed nozzle) or distance from object?
Making something plastic look rusty is a true art and I've seen some great examples on this forum.
I did a bit of googeling and I found this looking up rust effect:

It's called rust patina. It comes as an iron rich paint and a seperate oxidising agent. I'd also get the sealing agent so you can stop the rusting at just the right point. I can't wait to try out mine, I just ordered some as its perfect for a seperate project I'm working on
