Dana, you could always scrape out the moulded in stuff & put in bits of wire or whatever to replace it, looks a whole lot better. I did the airfix 1/24th P51 that way, not that there was much there to start with. It took nearly a month, but I have depth, texture & more realism than paint can get.
Use phone wire, florist's wire, stretched sprue, guitar wire's (for that convoluted hose look) bit's of plastic card, anything really as long as you get the right effect.
