Auto body repair & detailing: doing panel painting 93 GMC van, sand buff, roof gutters

Question
I have a conversion van, 93 GMC, that is 3 different colors of blue. Due to the van converter several bands and stripes from the roof gutters down to and including the full length lite blue (much lighter than the rest of the Dark Sapphire blue factory base van paint) runing boards with a matching light blue section of lower panels painted from the front to the rear of the whole van that run along adjacenet to the running boards/wheel flares. All these front to back sections are seperately painted with clear over, then and I beleive the van orginal D Sapphire base is also clear coated from the factory. When the van converter cleared each banded section they did by taping off along the edge of each seprate lighter band or section they added to the orginal base paint leaving tape edge lines in the clear along the edges. Which gives me a definite line. My question is I want to paint the running boards and this front to back section 8 inches or so wide that runs along the boards front to back. In an effort to calm down the circus wagon paint scheme with so many different colors, bands and stripes. Thinking if I painted this section and the running boards all the way front to back of the van back to the orginal dark blue it would calm down the multicolor nighmare. People tease me about never going unnoticed in this van I love so much. I used to paint Corvettes that I repaired back in the 60s and 70s, so the only paint I am familiar with is the good old acrlic lacquer. Spray sand buff - or shoot clear sand buff - if you do it right and work hard on the rub out you could make it beautiful, which I usually worked hard and did.
Problem is I know NOTHING of painting any kind of these newer paints and I don t have any kind of dust free invironment like a booth to do it in. What should or can I do ? Assuming I dont have the cash or trust to let someone in a shop do it ? Also could I or would it be a big mistake to do this painting by getting, if possible the factory color mixed in the old type lacquer that I know and can spray in slighlty dusty conditions ? I hate to go back wards by using a not as good material - as tuff as the current paint materials but I dont even know what kind of paint it is or how I would be able to spray it in my driveway with these currently used paints. In other words I like my van and intend to keep it for ever and I dont want to crow it up. Being handicapped its my 55 Chevy or prized Mustang convertible, I think you know what I mean. Any suggestions would be greatly appreciated.        Mike in Sarasota Florida.  

Answer
the area you want to paint must be scuffed and masked off. the clear coat finish that is on your vehicle is not that hard to spay if you painted cars before. The basecoat is alot like the old lacquer it goes on dry looking. the clear coat must must go on wet looking the better you lay it out the better it looks when dry. You can get fast dry clear that you could spray in your drive way on a nice day ask for help at your local Napa store on what kind of paint would be best for you.they should be able to match the factory color pretty good
