Hello:
I am experimenting with Tamiya rust weathering powders and would like to know if anyone can offer advice for sealing the powder to the structure with some type of matte finish or varnish. It may not even be necessary but I would like to hear your experiences. The powder seems to adhere (to painted styrene) pretty well so I am reluctant to follow up with any sealer for fear it may diminish the effects of the weathering. Once in place on the layout, the structures will not be handled.
Thanks,
Rick
