Just to add, I've used Renovo for years and I just don't think its made the same as it was, and if it is its now lacking.. It
I probably seal about 20 hoods a year now including my daughters E 350 Convertible and nothing protects as well as Fabiseal and Renovo doesn't last anywhere as near.
I think you would be mad not to use this. Most professional detailers I know use this now. 3 coats of Fabsil will keep your roof beading for years,.
I gave up on Renovo just not offering the same true bead value and it just doesn't last properly, it soaks and sheets and doesn't offer true 100% repellancy.
Shame I can't post a video of a Carbon Black Aston DBS Convertible I look after that insists I only Fabsil his roof as the beading is insane on it.
