its pretty simple, I just finished one yesterday using rattle can paint
1: Prep your surface (remove all oil dirt,etc)
2: Mask off (or remove) Items you dont want painted
3: Select your colors/ sticker patterns
4:.Paint the base coat (this is the color that will show up the least IMO)
5: Once the coat of paint is dry (in my case after 1hr) add your stickers how you please (keep in mind, the paint you cover up with the stickers is the paint that will show up when you peel the stickers off)
6:.Paint over everything with your next color
7: Repeat steps 5 and 6 for your other colors
8: .Hang it up somewhere to dry till all the paint is cured completely
9: .Carefully and slowly remove your stickers
10:.Profit
Stencils I used are the Swedish M90 pattern from
