Now you might be thinking, "Mattel lead-paint scare", but this isn't some consumer-advocacy site. See, every now and again I catch myself looking at my small collection of Optimus Primes, thinking how a repaint and a drybrush would really bring out all that detail on the bland grey plastic bits (especially movie Optimus). Considering the amount of disassembly and reassembly the effort would require is enough to put me off, though.
