Aviation skydrol. Just a drop where it doesn’t affect your paint or on a piece of rag. No birds will ever be a problem after that.

No. Thanks. Trying to send a reply to another member.

Almost there! Still got to do a final clean up.

That should have been noted on a landing gear swing test or plenty of them before releasing that aircraft to the owner. Hard to tell from my iPad and knowing the previous history of the aircraft. This was mine a while ago.

Oiler, clear hose from the lowest point or caliper works every time. Just make sure your clear hose stays on the bleed port and have another clear hose off the reservoir to clean container. You or somebody helping you can see the air come out. It's a bit hard sometimes on your hand.

Hello, Bonderite CIC33, 79, M-CR 1200, AkzoNobel Epoxy paint and primers. It's expensive, but its really good stuff. And I know, it will be nice if you could buy this product in smaller amounts.

Great work! Did you do all 4 bays? I have been looking at my outboard one and it looks perfect. Hate to do things half way, but I also don’t like the idea of fixing something that’s not broken. I have seen this with other fuel tanks on vintage aircraft way bigger than a Mooney were we mainly replaced the center section structure of the aircraft / fuel tanks due to be the lowest points were water and moisture rest for the most part. Lots of Sheetmetal work and then reseal. I am using AkzoNobel fuel tank primer on mine just for the age of this aircraft. When it comes to the Polygone… they just need to add a few more revs to it. It’s like using a low speed hand dryer. Also there’s some rivets that I am replacing on mine. There’s are a few leaks thru this rivets which looks like somebody tried to fix before, way back in 1993. Those rivets are located at the inboard side of the left fuel tank. Thanks for sharing your work!

More progress. Not much, but still progress.

That looks like damaged dome nuts. Maybe and depending on when it started at some point somebody probably used the wrong size screws damaging the domenut. That’s off an access panel, but I see a possibility that this could be your problem.

Right, that I will evaluate once everything is cleaned up.

Here’s a few. Not completely cleaned up yet. Also they used a few blind rivets in this tank. It was probably somebody’s first day or week at the job. And even with this bad rivets it’s been flying since 1968. One of those things.

Yes. You just have to know when to stop. Talking about rivets, there’s about 8 to 10 rivets in this tank that were unairworthy right out of the factory. I will add pictures of that later.

I haven’t got to the materials part yet. Busy with other airplanes. I will post the information as soon as I get to it. Now, here are some pictures of what using the wrong hardware ( too long ) to your access panels. can do, creating more leaks in the process. That’s also PolyGone at work on the access panels with original sealant.

Ok. Just to clarify and to add more information. I used Norton Liquid Ice Extra Cut. I used the polisher with a wool pad. I do have the foam pads. I did use the foam ones, blue, white, black, but the wool seem to be the one with the best results. Also this equipment I am using is very old. I am sure there are new options out there. The ultra fine compound I haven’t used yet. So this pictures are before even using the ultra fine compound. The small polisher I used over the round head rivet areas. It might take a bit longer, but it doesn’t cut or remove the paint off the rivet heads.

I did use their foam pads too. That for the areas with flush rivets. For the areas with round head rivets I used a smaller polisher. Spray light water as you go. It makes a big difference. I will add pictures of the two I used later.

Just Liquid Ice. It works great!

Actually, they responded right away to my email. 90 bucks per gallon.

Great! Whatever saves me time will be great! Got other projects going on. I will post the results / comparison with or against Poly-Gone. Which have work for me in the past. It just takes time. Thanks

That’s the website for D-Zolve.

Can you buy D-Zolve in smaller amounts or quantities? Like, a gallon should do one side.

Polygone works. You have to have the right temp and a lot of patience. Works best with the original sealant. It doesn’t do well on the patches. I had to pull or scrape them off. Lots of patience. I did used aluminum tape around the access cut outs. That will protect against Polygone or any other stripper. I am painting that section on both wings later on.

Polygone works. You have to have the right temp and lots of patience. The reason I mentioned temperature is because I am located in a cold weather area. This would not matter in hotter or warmer environments. Works best with the original sealant. It doesn’t do well on the patches. I had to pull or scrape them off. Lots of patience.

It does. You either like to do this type of work or you absolutely not.
