I'm not extremely familiar with the Duragloss line but don't they have multiple polishes and sealants (called polishes?)
For a while they had a line specific for cars without clearcoat and one line for cars with clear. I'm not sure that's still the case.
I looked last night and I still have an old bottle of Duragloss, I used to really like it, it's good stuff. I'm just a junky when it comes to trying new stuff and it's kind of gotten pushed to the back of the cabinet!
