I'm making one of the new Airfix BE2c's. Airfix suggest using Humbrol 98 Chocolate for the engine covers, and upper front decking. I can only find it as an enamel and I've pretty well converted to acrylics. I don't think it's available from Humbrol, so the question is, is there a good acrylic equivalent. For brushing so Tamiya is probably a no no.
