Likely, you'll get paid for a "standard" roof replacement and you'll have to pay for anything else. I called a local company about FlexArmor several years ago on my old Komfort. IIRC, it would have cost about what my FW was worth to replace the roof, and that's =without= them doing any repairs that they find after the old roof is gone. IIRC, it was at least 50% more than a rubber roof. Given that you've got an orphan Cameo, I'd think long and hard about how long it's going to ultimately last before dumping that much into it. I doubt you'd recover your OOP $ on a sale, even fairly quickly afterwards. Just my $0.02...
