SWeathering Powder adhesion

I have recently been trying to apply exhaust stains to my current build. From any tutorials I have seen, they go on dry and a brushed in, but when i do this they just slide around and don't stain the aircraft. This is the same for scraped-up tamiya weathering powders and hard pastels.

Any tips?

Thanks

I use pastels, rubbed down with a Mk.I finger

Pigments can be brushed and worked onto a matt surface, which is a bit more 'grippy'. They really need fixing, but provided you avoid handling they should be okay.

I used Humbrol pigments to try and get a rusty look to the exhausts on this Tiger 1 model. It was also worked into the cables.

I tend to use cotton buds to apply the pigments. Paul's point about a matt surface is good. Also you need to spray a coat of varnish or spray coat as brushing varnish will make the pigments run. I haven't tried pastels on models yet but they do blend easily when rubbed with a finger. So you might follow Ratch's advice.

Thanks Ratch for the tip. Mark 1 finger did the job.

I had already covered the thing with a gloss varnish (of dubiuos origin hoiked out of the cupboard) which was probably causing the problem.
