its kind of an involved process and is easier if you have 2 people, but you can do it alone, I did it alone on the last two batches I did of approximately 15 total cars...
first spray all the decks with floquil primer and let it dry. Once they are dry spray one at a time with floquil depot buff. You don't want the depot buff to dry, but you do want it tacky. You can experiment with the drying of it to see what works best, because the whole process hinges on this part. Next take floquil roof brown and a tooth brush. Dip just the tip of the brush in the roof brown because you don't need much. The more roof brown you put down the darker the deck will be. But you jsut scrape the toothbrush widthwise aacross the deck, with the depot buff tacky you scrape some of it away and expose the grey. Varying the pressure you use will yeild different results also. Butyou jsut go down the deck and make sure you work in the same direction and work widthwise.
SO in short,
Shoot all decks with primer and let that dry
Shoot one deck with depot buff and let it tack
Scrape with roof brown and toothbrush to expose the primer and put some dark brown
If you have a second or third person, they can scrape the decks as fast as you push them out, otherwise you will have to do them one at a time by yourself.
