Hello from Switzerland!
I'm about to make my first tarp and read tons of stuff about everything and found lots of information on this website and I thank you for that.
The only information I need is related to the sealing of the seams.
I'm making a tarp for a military/tactical/low-profile-ish application and I need the sealing to be matte, to avoid sun reflection.
So I wanted to know if DIY sealing with mineral spirit and silicon does shine or not. And what about SylNett's sealant? is it glossy/shiny etc?
I was also curious about the matte aspect of sealing tape, for example the one made by 3M. Anyone has some experience to share? I have a military gore-tex parka and all seams have a great matte sealing tape but it's impossible to know what brand they used.
