Pretty much the same stuff AFAIK.
Here's someone doing it on a Cayman with the Rust-Oleum stuff and the same technique...
Well yeah, but they were doing racing stripes, not emblems... More importantly, they were spraying on the paintwork, which is exactly what I did...
Had it for 5 months. I wash it, but the guides specifically say to prep the area by removing any wax from the area.
Yes, it says to mask parts off, but that is just to make it easier to remove / clean. It is designed to be used on paintwork, not just emblems and plastic trim. As such, there shouldn't have been a problem with it getting on my paint. In theory (apart from giving a shoddy finish) it should be perfectly suitable for spraying my entire front bumper, but instead it has just melted it...
