The methods talked about here are different than the surface coating you used on the ice chest. Our goal is to get the silicone to impregnate the threads of the material and not just sit on the surface.

I imagine that all consumer silicones are RTV (room temperature vulcanization) since we're not applying heat to turn the product from liquid to solid.

So has anyone tried GasX as MacEntyre suggests?

It's got to be the most expensive source of "Simethicone" available... manufactured using pharmaceutical GMP standards by Novartis. However, I suppose you could carry a couple of tablets in your backpack, and mix it with denatured alcohol to have a small amount for a field expedient patch.

I am about to do my first DIY Sil project tomorrow. I started a thread to tell about it http://www.hammockforums.net/forum/s...747#post415747

I will update how it goes on there. I plan to use the 100% silicone and oderless mineral spirits....

If the fabric isn't treated with dwr, it should be pretty absorbent. I'm betting a thin enough mix could be brushed on and still fully absorb. You'd might want to hit both sides, but I bet that would do the trick. It gets mashed in even more as you're trying to wipe off the excess.

**harrell79cj5** · 02-24-2011, 15:38

Yeah, that is kinda my plan, to brush on both sides. The fabric doesn't seem to have any kind of coating, in fact BWDD states it as not downproof, so most likely pretty absorbent.

If a fabric has a coating(for fire resistance or dwr) do you then have to wash it first or will it still bond to the fabric?

**warbonnetguy** · 02-24-2011, 19:40

i don't know, the fabric i used was non-calendared without dwr

**JohnSawyer** · 02-24-2011, 20:41

I did a patch of DWR, it soaked up the solution nicely...

This would be a great cottage industery business service! Does the cost of buying non silnylon and coating it actually pan out, better than just purchasing silnylon from the start? Mind you, I have my own camo ripstop waiting to be finished and DIY sealed.
