Some of them are store bought. SOme are custom cut by me and free handed. The taping process is very tedious. Its all in the prep work. Even after you have to clean the edges with a q-tip and goo-gone. You want all the lines to be smooth. I do not suggest trying this at home. I swore probably 1000 times. Variety is the spice of life! Hope you guys enjoy. Stay tuned for daily progress.So you're using your decals as masks? Just painting, then peeling off the decals?
