If two stage looks like one stage and is much more durable, why use it?
If you have a big block car you're more likely to understand the question.
You can't tell it's two stage, and with the vintage clear is looks spot on.
Just a thought. My vehicle is not going to spend it's life on a trailer, so while trying to remain pretty much as produced, I still want something that will also clean and detail easy. This is the answer, and the 9000 is the ford black, however as you noted, I elected to go two stage for obvious reasons.
