RE: Another large scale Impreza project
Re: paint removal from plastic just thought I'd add that you can also use "odor free" EZ Off oven cleaner to remove several different kinds of paint including enamel from plastic (I've used it on styrene and ABS). Just have to be patient to let it soften the paint, then I've used an old toothbrush to remove the paint under running water, with a little dishwashing soap.
Cool project!
