A downside of silicone caulk is its softness, which I think contributes to the fabric remaining relatively stretchy along the bias (diagonally). Looking at a few datasheets, it seems that harder silicone formulations contain more fumed silica (cab-o-sil) filler, which is also commonly used to thicken up Epoxy (and toothpaste). The GE caulk I used has around 5-10% for a 20 shore A cured hardness, while slightly harder silicones have 15%. http://www.cabotcorp.com/~/media/files/ ... rubber.pdf has a graph indicating that 30% fumed silica by weight would result in a 46 shore A hardness. That might be a bit extreme, but I could see adding 5-10% to silicone caulk work well.

Reviving this thread. Foilholio can you update us on how the shoe goo/toluene coating has held up over time?
Also has anyone any experience with CRC aqua armour which seems to be some sort of naphtha petroleum waterproofing spray. It looks easy to apply but may be only a waterproofing rather than a sealant as it is advertised as breathable.
Cheers

Sorry I havn't actually used that kite much anymore so it is not a good gauge on the longevity of the coating.

Its based on chemical nanotechnology......so it must be good. That statement is enough to put me off. Why do manufacturers feel the need to add this crap to their marketing. Just makes me suspicious that I am being taken for a ride

Yah I know! Everyone knows it's Quantum Physics that makes stuff waterproof, not chemical nanotechnology! :lol:

Sail & Kite looks quite similar to a silica nano coating I spray on my truck, called Permanon. It works pretty good on hard surfaces, but I don't think it would improve the surface characteristics of a kite. I might try it on some ripstop nylon to see if there is any improvement. If I do I'll report the results.

Many of these spray on products are designed to improve water shedding or repellency . In particular many of the cloth based sprays are designed to also maintain air breathability or flow for wearer comfort. With kites particularly foils you want to prevent airflow. Waterproofing is more of a side effect to a good coating.

I suggest you guys try the coating I used, as it worked very well and is quite cheap.

Anyone know if the ozone chrono v1 fabric was nylon or polyester or a blend, or? I’m thinking about giving the old chrono v1 a fresh outside coating of styrene butadiene rubber (marine goop) thinned with xylene and toluene. Nylon should be ok but extended exposure of polyester to these thinners may be marginal according to http://rfelektronik.se/manuals/Datashee ... tguide.pdf

The coating on the inside of the chrono may be styrene butadiene rubber or silicon as something like that is starting to peel off the fabric inside the wingtips. It is not peeling off in other areas yet, but I'm looking to reduce the kite fabric porosity and extend it’s life.

Doesn’t the toluene or xylene flash off in a few minutes?
Either way I would test the mix first on a small, easily repaired part of the kite or a patch of the cloth.
