Thats approx 25%. Within a couple weeks of finishing the process of prime- epoxy., I noticed clear coat lifting on half of the needles. The clear cost lifted everything from the bare wood.
Mind you Ive been doing this same needle for 10yrs or so and the only difference done was this excessive soak. Immediately I went back to my proven.method of 30minute cold soak in 60/40 spar varnish and mineral spirits.
BTW I ended up scraping off all the needles to bare wood and let them dry for a month. I weighed them first then after. Found a drop of half the added weight from the sealer. Fellow builders have done experiments in sealing soak times and found no benefit from soaks longer than 10 minutes.

I heat some of my plugs, specifically maple darters to be epoxy sealed. Because epoxy chemically cures there is no off-gassing issue later. The result is a super strong plug, especially considering the bottom lip takes abuse and maple is not sealed well splits, I find the extra time to epoxy seal darters is worth it for me. Ayc darter lips, even if sealed this way still break.
