I've been using AIM weathering powders and generally like the results, but when I overcoat them with Dullcoat the lighter pigments seem to get toned down to an unacceptable level. I just recieved a couple cans of Krylon Artist's Reworkable Fixative and don't like the results from that either - it's worse than Dullcoat. Too shiny and removes the dusty, lighter colors. What is everyone else using? I know I can leave the powders as-is but most of this is being applied to rolling stock and engines, so they are handled more frequently. I've used an airbrush with Pollyscale flat coat but I was hoping to find a quick alternative to firing up the airbrush! Thanks for any help!
I apply the weathering fairly thick in anticipation of the Dulcoat toning it down a bit. It's tricky but I'm able to get good results. Also be sure to apply powders to a dull surface. It sticks better.
I use the Bragdons weathering powders and have not noticed any change in the effects after application of Dulcoat. You can normally get a better application of weathering powders if the model first gets a light application of some sort of flat. I have never been able to get the control from a can that I get with an airbrush so I always use the airbrush.
I've taken a different approach. I'm either hitting a car with an alcohol fade (to etch the paint) or a coat of Dullcote, and then applying the weathering powders. Gives it more tooth. You can rub it off but you actually have to work at it. I've never had any luck with putting fixative over it and getting the look I want. I really like a black powder rub over a steam locomotive to get the soot look on the boiler and you can't really seal that in. It's just easier to reapply it if you have to.
I hit the surface also with a light dusting of Dullcoat then apply powders and lastly another light dusting of Dullcoat.
