How should I clean paint off dual scoops?

Thanks to "crackedback" I am now the owner of a decent pair of dual hood scoops, but they have multiple layers of cracked/chipped paint. What's the best way to clean this stuff off? I'm thinking chemical stripper, but I'm afraid it might damage the composite polymer they're made from. Sanding would take me until I'm old and grey. Pressure washing maybe?
