wound up using the duplicolor paint shop lacquer system.  it is premixed and we used 2.5 qts of red. 3.5 qts of white. 4 qts of primer, 4 qts of clear, 5 cans of duplicolor  self etching primer for the bare aluminum. 1 gal lacquer thinner for cleaning and wipe down purposes, 2 bags of white shop rags, 2 bags of tack cloth, 3 strainer kits,  1 pack of 600 paper, 3-4 sheets of scotch brite scuffing pads. couple rolls of blue tape, with discount it wound up at about $350 for paint and materials.  I think we could have done it cheaper if we used a solid color and could have purchased it by the gallon then i bet we could have done it for $150-$200 but my son wanted the two tone paint scheme.  My son paid for the paint and I bought bought a Vaper HVLP  two gun set  from Autozone for $99 as a back up set up since on thursday the 3 gun set up i ordered from TCP Global had not arrived yet.  We still didnt have it  on friday when we started painting the primer and as luck would have it, it arrived on saturday afternoon.
the temperature was nice to us and even with the fan going pulling filtered air in from the outside when we were painting the primer  the friday temp inside was 70*, saturday was the red color coat/clear and it was 68*, and sunday was the white color coat/clear and it was 64*.  2 hours after we got done painting we went back out and cleaned up and then turned the heat on in the garage and its a comfy 69* out there.
overall we were happy with the paint product and we got really good with the HVLP gun.  no runs or sags in the color or clear coat and our initial screws up with the primer we sanded out.  our initial problems with the primer came from more of staging issues then anything else meaning the hose got caught on a ladder and  made the gun move funny.  so after the priming was done, the next day we did the lower coat and after seeing how it important moving with the gun was i built some scaffolding to put on two ladders so we could paint the top and that worked perfect.
