I just did my first sewing project, I actually just modified my existing wind jacket. I'm very tall and on the thinner side so it's hard finding clothing at a reasonable price. Either it fits in the chest and is too short in the arms and length or it's long enough but fits like a sail. So I "took in" my existing jacket, that I had previously treated with DWR. I used polyester thread.
Here's my question, now that I have new seams what can I apply to a nylon jacket to slow leaking at the seams? On my tents I've used the silicone caulk and white gas but I don't know if that's okay for a jacket. Any ideas?
