Holy Proseal, Batman!
Mixed up the Proseal and slathered it on. Riveted the three inboard ribs this morning in a 5 hour session. That included all of the cleanup required when messing with the evil goo. A few of the rivets are ugly, but not bad enough to redo. Fortunately they're all on the bottom side of the wing. Go figure, I thought that side should have been the easy part.
Had to drill out a couple. They just weren't going to work.
After a break for lunch, launched into it again. Another 5 hours! And I'm trashed now. Didn't think it would take that long, but when I hit the stop button on the timer, it was 9:57 total. Got the other two inner ribs done, plus the outboard exterior rib, and it's nose reinforcement plate. It was a mistake to launch into that last rib, should have waited till tomorrow. Wasted some time cleaning tools when I realized the nose reinforcement plate still needed doing, so the tools got mucked up again. After 10 hours, I'm trashed. Didn't get a run or bike in today, but it feels like I did a race!
Doing fairly well on Proseal. Still have about 3/4 of the quart left. Should easily do the other tank and all the trailing edges, assuming it's not out of shelf life by then. Today started with about 2 cc of the black part. This weighed in close to 10 grams, so used sticks to draw out 100 grams of the white part into the mixing bowl. This was just enough to do three ribs.
Used lacquer thinner as a cleaning solvent. It seems to work better than MEK, but it smells bad. Actually it smells amazingly like 100LL. It doesn't take a big leap from lacquer-thinner-smells-just-like-100LL-works great-for-cleaning to won't-this-melt-as-soon-as-it's-filled-up-with-avgas? The answer is obvious once you start cleaning up the tools afterwards. It's good for cleaning, but requires elbow grease and many passes. And that's before it's cured. Just don't scrub the inside of the tank while it's full of gas and dissolved ProSeal shouldn't be an issue. Just try to get cured ProSeal off your clecoes two weeks later!
Here's an interesting data point. I left the gummed up clecoes in a jar of lacquer thinner for two days. The ProSeal set up, immersed in lacquer thinner! It was just as hard to get off as if it hadn't been soaking.
