GoLite’s 15D Tent Fabric

John,
Silcoated and PUcoated are different. For PU coated, there are restorative treatments like Tent Sure by McNett. If you try to coat PU coated fabric with silicone, I think you will be disappointed. For restoring DWR there are sprays with silicone and without. Kiwi Camp Dry, for example, comes both ways. Since there is a choice, I use the 'without' for PU coated fabric, and the 'with' for silcoated fabric.

I think it is too soon to know how durable the 15-20 denier tent fabrics will be. I have a 15D Aussie tent that has only been out for a few weeks so far. Haven't seen any silcoated 15-20D yet, but it should be doable. The consensus here seems to be that silcoated nylon is stronger than PUcoated nylon, other things being equal, so it might make sense to silcoat the low denier, if a highly water repellent silcoat is available. Roger Caffin has told us it is not in the USA due to environmental regulations. So it depends on whether someone elsewhere will to do it.
