I read the following post and wondered if I could use the same method on a tent that was formerly treated from factory with a polyurethane coat.
What is the best way to re-waterproof a nylon tarp?
My tent is an old eureka acadia 2 and all but a few small remnants of the coating is gone. It's only ever been used a handful of times, but it hasn't been stored well for the past couple of decades. No rot, holes, or mildew, but I've washed it and it took all the coating off. I'm considering restoring with gear aid pu coating, but wonder if the silicone/spirits solution would be better.
Would it even work since it's not silnylon?
