I want to save my 1-2 person tent. Fabric is 190T polyester PU. During rain the fabric got wet and had some water inside,.. It seems it is not seam problem, it is more coating issue.
I dont know what coating should I use? I could use some wax based spray for outside of it, but dont know should I apply, paint base layer of silicone protection on the inside or outside and then wax?. If someone has experience with that and will share tips appreciate it.
