I have a serious problem with my soft top on the Boxster, used Renovo to clean the roof, then reviver to revive the colour (Blue) and then selaed it with their water proof product. Well the outcome was a disaster, the roof is now so hard, it's like a hard top, it is so stiff, when I open the roof, the rear cover cannot close as the roof will no longer close correctly.
I just read an article on the Detailer forum and a guy has exactly the same issue as me. Like you guys report here, the reviver has left streaks everywhere and a line where I started painting with the brush, the top is also shiny, like a pair of 100 year old shiny worn trousers. It is a joke.
I contacted Renovo, they have offered me a full pack of replacements to do the job again, I was about to do this when they sent me an email that said "Please respond to this email to advise that you are willing to accept this offer to rectify your problem in full and final settlement of this case?" That made me suspicious this must have happened before, blow me down, I searched Google and there are similar stories on dozens of forums.
I put the car in our local valeting detailing guy who specialises in restoration, I was having the car Ceramic Coated and asked him to sort the roof as well, unfortunatley he called to say, hmm, Renovo, nothing he can do with the roof.
Renovo have totally destroyed my roof and now I need to get them to replace it.
Dont use Renovo reviver, EVER.
