Not cost effective
Had high hopes for the renovo range but left dissapointed. Followed instructions to the letter including their youtube videos. However, I found the cleaner to be underwhelming, dye to be difficult to work with and the waterproofer to be average. Note: on the bottle it says Renovo recommend two coats of the waterproofer (and dye) and a 500ml bottle was only just enough for one coat on the hood of a Mini cooper.
The renovo products including this waterproofer take too long to work with and the alternatives from the major detailing brands are much faster and easier to apply and in my opinion, more cost effective. Did the job this time round but I won't be using them again.
