Default sloshed tanks...again

Well after several years of dealing with sloshed fuel tanks on my RV4, I have decided to deal with them once and for all. It should be noted that I added fuel filters several years back and also finger screens inside the tanks.
Even though they look awful, I have never found any slosh in either of the fine bronze filters.
Reading previous articles on VAF about sloshing compound, I was made aware of Paul Beck. He operates WeepNoMore, a Company up in MN. that removes slosh and reseals tanks. Paul received my tanks yesterday and has started stripping them. He sent these pics.
I will update his progress.
I know there are several older threads that document this operation but since there are still questions popping up about slosh, I figured I would add my 2 cents...

Wow, the tanks on my 1993 vintage RV-6 are sloshed but look NOTHING like those.

There is slosh compound carefully applied along the pro-seal joints and the back wall, nowhere else. I watch them close as the SB suggests, but I haven't had even a tiny bit of the compound show up in a screen or sump.

I've heard nothing but good things about the work at Weep No More, you'll have some nice tanks when they come back.

And my wallet a bit lighter....
If my tanks are clean and tight, I will be a happy camper.

Default Tanks

Dave,
Thanks for the info/update.
My RV-6 tanks from 1994 were sloshed and leaking fuel. After considering the amount of work involved in repair/fixing them. I had Evans build me new ones and after fitting them to the plane, I had them painted to match.
My wallet was lighter too but I had new tanks!
I guess I had more money than time...:-(
The fitting to the plane was a small job compared to chemicals. Vans actually sells a replacement parts kit with oversized skins for a trim to fit install. I had the kits shipped to Evans and he shipped the finished tanks to me.
Just another option for sloshers to consider.

Default Why does this happen?

That looks terrible. Maybe this is a silli question but how does this happen? And why does it not seem to be a thing with 45 year old Cessna's? Or am I just misinformed...

Apparently it was an issue for some Piper aircraft. Haven't heard that Cessna used Sloshing compound. I have read that if the inside of the tanks was prepped properly, the slosh adhered better. Mine was hit and miss. I remember removing a large flake a while ago.

Default Sloshed tanks

I just installed my -4 tanks after having Paul @ weepnomore remove the slosh. The tanks look like new inside. Excellent service and great workmanship from Paul.

Don't Cessnas use bladders inside the wings for fuel tanks?

(maybe it depends on the Cessna)

To my knowledge, Cessna hasn't used bladders for sometime. The 1978 182RG had bladders while the 1979 model used wet wings. All of the late model 172s have wet wings.
