First, let's start with the paint. Rattle-can jobs aren't top quality, but can be effective and CAN look better than that. There's several areas of the bike that look as though they were not prepped propperly. You need to go out with some 180 grit paper, after your paint stuff cures (about 7 days), and knock off as much as you can. Try to work it down to the original paint, if you can. Then wet sand with 400 grit, 600 grit, and finally with 1000 or as high as you can find...all wet sanding. This will get you a very nice, usasble finish. Next, go out and buy new rattle cans. This bike should require about 4 cans of primer. With your color-scheme I would go with black primer. If you repeated the color scheme, I would use 5~6 cans of the silver and 5~6 cans black. Get 10 of each...you an always return what you don't use.

NOTE: $.98 Wally world paint is crap. Go someplace and get Krylon or another quality spray. Expect to spend between $3 and $5 per can.

Start priming. Apply a thin coat. Wet sand with the 600 grit, then with 1000. Repeat until you have a glass-smooth surface that shows none of the original paint or tinting. Let the primer cure over night. Then start applying the new colors. Apply thin coats, at least 10 but continue until you have a deep finnish with no evidence of the undercoating.

Things you need to keep in mind:

You're not moving your spray can fast enough. See those streaks in your paint? They're there because you're moving too slowly, allowing paint to build before moving on. Then you can't keep it uniform.

You're holding the can too close. Again, look at the splotches...they're narrow and elongated. This means your nozzle is FAR too close to the surface. Spray between 12 and 18 inches from the surface.

Mask the surrounding areas. The overspray on your frame, exhaust, and surrounding areas looks very poor.

Do not apply decals until your paint has set a minimum of 4 weeks. They can be quite damaging and they also prevent the paint from curing propperly.
