I think I would be tempted to paint the roof first with black fabric paint to get rid of those marks as you won't ever get an opportunity to do it again as it cant be painted onto silicon.The beading aspect is impressive but does it still allow the fabric to breathe? It was my impression that it isn't the fabric that is supposed to be waterproof but the rubber layer beneath??
Oh yes it’s a tent fabric so it is breathable and to be honest it’s worn off already. You have to do it every year so I will try the dye aspect this year and I might video it because it was something I thought about afterwards so you have a great mindset, thank you for reminding me. There is a rubber membrane underneath but it’s just nice if the water sits on top and beads off as here in the UK it rains a lot and I like to drive as much as I can with the roof down. So after 5 minutes of driving the roof is dry. Thanks for the comment 👍👊🏻
Yeah I applied it once let it dry because it was quite sunny and then started again from the other side. I was not stingy with the application. I felt the more I put on the better it would be👍👍
