Ok I think I need remedial modelling class 101, I spray painted my abrams in dessert sand acrylic. decals applied, and was putting a wash through the area (which was looking really good) until the paint started to lift a little. Was I suppose to put a seal of matt varnish on this or something???? Totally bewildered and banging my head against wall. please advise asap. Thanks in advance
My response will be different depending on the type of wash you used.
You base colors were acrylic, so if your wash was acrylic also, you need to have a clearcoat in between or risk dissolving the previous layers of paint....which is what sounds like happened.
If you used an oil-based wash, perhaps you didn't leave enough time for curing in between. The acrylic paint needs to be completely cured before using a wash directly over it. I like to clearcoat all my models after painting, but others believe it's not necessary if you switch between acrylic and enamel/oils.
