this is what my top manufacturer (electron) recommended for my Vinyl convertible top
View attachment 1716542834
I have had my top on since 2020 and have used it a hand full of times. The top is normally down and the car is garaged. Temperatures in the garage range from 20f to 85f and the humidity range is 10 to 65%
I rarely use it as directed meaning most times I'll use the protectant without first using the cleaner.
the top looks good and is soft and supple
BTW if your top installer says "Oh that wrinkle will come out with heat and time" It won't! it was installed wrong!
