I have been using Tamiya paint {Tamiya models using their call outs}
once I have painted the models I have dry brushed{little paint on the brush, mainly rust, silver etc.}
then used the Tamiya powders.
I tried using mineral spirits but neither my oil paint and the Tamiya paints will suspend in thet mineral spirits {my oil based paint can be used in water}
when I use Isopropyl alcohol {70% with little paint} it goes right through the paint {some have been sitting for several weeks so the paint is dry}
what should I do? seal the first layer? if so with what. if not, what should I use for the wash?
thanks,
