It darkened my bimini and I rolled too much on, some had to be scraped off with a putty knife. Just be aware that this is a very thick coating
Edik Molitov –
My fabric looks like new now. It looks darker and refreshed, like it’s hydrated or wet.
Evgenii Volkov –
It takes a while to melt and apply but it’s worth it for the durability.
Fernando Alvarez –
Perfecto!

I had my doubts but fuck was I wrong. This goes on thick and will NOT wear off. I mean, rigging rubbing across it all day and it’s still minty. Well done sirs.
