Here are my two most recent builds; my take on the ESV and ESV 2 knob.
Because I use Lazertran waterslide injet material, which requires no overcoat, I am limited to an off-white to make the paper fully transparent. I also like working in color so this isn't much of a bother to me. I use a Rustoleum that I can bake at about 200f for 10 minutes or so, then apply the decals and a Rustoleum clear coat. The decals are ready for clear spray after about 12 hours. This I can't bake as the decals start to brown even that low, but a heat shrink gun helps treat the clear coat.
Because these are the fancy grade pedals I added a step; I used a pearl metallic Rustoleum to give it some sparkle, which is mostly clear, so it works well on this. This gets baked as well, and is under the decals but shows through nicely. I don't work for Rustoleum; its just what's readily available at the local Homey-D. I'm sure anything similar would work as well.
Another little heads-up is to wear a white shirt while painting these; a black one sheds like crazy and will get on the finish. White sheds as much, it just isn't so visible on these. And I've made adjustments on the Fuzz Face one to lower the knob labels and increase the fuzzy font size.
I did try automotive paints, but I couldn't get the Lazertran to adhere well to it; much more bubbling.
