Thanks to all for the different ideas for metallic paint!
there's a bunch of smart folks on this site. After some consideration I have decided to to use the ACE paint, mixing the aluminum paint into the color until we like it. My reasoning is that the metallic particles in the paint are super fine and allows the paint to dry smooth. The metal flakes from LOWES are not so fine and will leave a texture (the sales guy said he used some when painting a table and it looked cool, but was rough), and metallic automotive paint is just too expensive for me. I'm leaning towards spraying the color as I think rollers and brushes will leave marks.
I need to make a plan of action on the rear wheels before I can paint anyway, Ol Trunt's strategy seems the best way to go, so I'm looking at fenders on everything I see. The tanks also need to be hung and plumbed, so the past two nights I've been laying under the bus mocking them up. The plan is to build some belly bins around them to protect and maybe help with some drag (as well as provide storage). Hopefully there will be pics cominng soon.
