I'm rebooting this thread for a couple of reasons. Firstly, a product I've used that doesn't build up on the edge of decals, or discolor plastics is Meguiar's Ultimate Fast Finish (G18309). The stuff is an aerosol that literally is wipe on, wipe off. Not really durable, but very fast and easy.
Now the second reason is I'm looking for thoughts on whether or not to strip all the decals off. I just spent the day cleaning and detailing mine (Granite Crystal) and I found the edges of the decals are a potential eyesore. They were trapping bits of clay bar and making white strips along the decals. Not a good look on a dark paint job. I was planning to use NuFinish because it's so durable, but scratched that idea as soon as I saw what the decals were doing with the clay. I'm sure NuFinish would leave a bunch of white chalky edges.
On the dark gray metallic, the decals are barely visible anyway... so I'm thinking of peeling them all off. What say ye? How many people are peeling the decals, or ordering trucks without them?
