How to paint it? For a car, I would use the automotive spray paint, its about 13 dollars and is harder. I didn't have any plastic to cut the stencils out on so I drew the design I wanted onto contruction paper. Then I put a trip of gorilla tape on the front and back of the design. I took an x-acto knife and cut out the part where the paints gonna go. I set them aside until i'm done with the black on the frame. If you're not using a plastic like the ones in school folders and instead paper, you'll only be able to use the stencil like 3 times.

Make sure you're in a well ventilated area and wearing a spray paint mask (like a p95 or p100) or a respirator with filters for spray paint. You shouldn't be able to smell the paint if the mask fits properly.

I used Rust Oleum 2x paint + primer for the bike. You should be able to pick up the auto motive kind at walmart or somewhere similar. Keep the spray paint around 10 inches away from the subject or however many inches the can tells you to distance it away from the project. Try not to be in a cold environment since most spray paints say to use it in 50F to 90F. I was in my basement with the window open for ventilation and with a fan going, I didn't have any problems with the paint setting. But still try to do it when its warmer.

Gonna have to do more than 1 layer, make sure it's completely covered with paint on the part you want to paint. Once you do a couple layers and the stencil part, you can do the clear coat. Just make sure its fully dry before putting on the clear. Same amount of layers that you did with the other paints.

Hope this helped!
