Any suggestions on how to spray paint a picket fence?

there are plants and bushes on both sides of the fence and I would like to know how to protect them. Are there any things I would need to know, such as preparing the fence? I will appreciate any advice you have to give. ThanksAny suggestions on how to spray paint a picket fence?
dollar general and other doolar stores sell plastic painters tarps for a buck and they are about 20x20ft.walmart also sells them for about 2 bucks, cover your plants with these. as for preparing the fence, go over the fence with a wire brush and paint scraper to remove all loose paint,if there are any broken or loose boards repair or replace them before painting, use a good outdoor porch and trim paint,walmart sells a good one for about 15 bucks a gallon and it has a 15 or 20 yr. warranty.Any suggestions on how to spray paint a picket fence?
Go to your applince store and get some refriderator boxes and break them open[so they are flat] slide them between the fence and the plants and pull them down slightly [with tent stakes at the bottom and twine and tent stakes at the top] you now have a cardboard shield to protect your plants while you spray paint] A more expensive version would invoulve a roll of plastic sheeting from the hardware store they sell thin plastic tarps that are 20'x 100' for painters to use while in the house to protect the carpet they could just be draped over the plants while you spray the paint.
Put a piece of ply on the opposite side, a tarp on your side. Turn the spray nozzle horizontal, and do the sides first.
