aircraft painting advice

I'm trying to paint an aircraft created using FSDS. As you all know, FSDS doesn't give me the ability to have reflective textures like GMax models do. So does anyone have any techniques or advice to help me create shiny or metallic looking textures for my airplane? Also, is there any way to increase the reflectivity or lightness of FSDS textures in the flightsim (just thought I'd ask anyway)Thanks
