I have had good success both powder and liquid back in the day. Now, I don't hunt on rainy days.

As I stated earlier I really don't think it matters much. Attached are a couple shots of a test I did a while back.
Feathers were quite wet on the one arrow. Didn't shoot it through chrony but it was 18 or 20 yds where I practice 98% of the time. It stayed with his buddies. Surprised and pleased to clear that issue out of my head about WET feathers.

If I know it's a rainout day I won't go hunting because of washed away blood trails. But if a day of hit and miss showers I'll stick it out and get wet knowing it'll pass.

Are those arrows sporting broadheads? Field/target points fly good without fletching at hunting distances.

That said, my biggest problem in wet weather is my eye glasses. They didn't come with windshield wipers so when they get rained on I can't see.

So dont laugh please-

Years ago i was on a hunt in Sika country and we had a helacious noreaster come through pouring buckets of rain in which we were going to hunt in anyway....My partner in crime shows up with a 50 pack of Trojan condoms-Unlubed of course.

Well we each had a dozen broadhead arrows in our quivers and proceded to add raincoats to each one. Needless to say our feathers stayed dry.  Not only that but reaching back, grabbing the nock  and loading an arrow quickly  wasnt hampered in the least......

  sorry but that's a classic! 

Dang I had no idea!!!

My buddy and I had some white powder that was for water proofing feathers we were on our way to Canada to hunt bears and we started thinking crossing the border with white powder in a couple of containers dont look so go so we stopped and tossed it out . I have never used it since. Tuned arrows should fly good even when wet .

I have always used   UNscented Free Hair Spray .   Works well  except in pouring rain , and I dont hunt in pouring rain as it erases blood trails JMHO. 

Since I use a glue to attach feathers, I'm not worried about them falling off, I like to use a spray like Scoth guard, Camp dry, etc. It doesnt take a lot. Ive never had a feather fall off like that.

I have used feather dry for years great results. 
I started about 20 years ago,  get an empty Pringles can, use a broadhead arrow punch hole in lid.  Dump the feather dye in, then with a completed built arrow, slide it through lid, put nock/feather in, secure lid, shake once, wait few seconds, pull arrow out, and tap.  DONE
