Renovo Ragtop treatment

Gave the Ragtop(S4) a complete three stage "Renovo" treatment over the weekend- (Cleaner, Reviver and Ultra Proof) Well chuffed with the results.

But after it dried up i noticed that there is still a couple of spots slightly greyish. Thinking of giving them another coat of reviver, but not sure how this would work after it had a coat of Ultra Proof? I'm also a bit worried if "spot coating" might show too much? Any advice from fellow Renovo users?

The ragtop is Black BTW.

I use Mothers on mine, so I cannot offer real advice. I tend to "overdo" it a bit with the last coat, but my roof still looks perfect, so it probably does no harm.

I use the Autoglym reviver, which does tend to be a bit useless once the Mothers is applied. You may have to go through the complete process a few times to get the desired effect.

Cheers Eric,

Think i might leave as it is for the rest of the season and then give it another full treatment again next spring.
