Stuff in gas tank

1358 Views 17 Replies 9 Participants Last post by  ZXtasy
I'm cleaning out my tank with apple cider vinegar and rocks and I have a layer of something coming off from inside the tank. I'm assuming some sort of liner. My plan was to get all the rust out and then use red Kate to cote the inside but now I'm worried that this tank is useless. Any ideas?

Try soaking a piece in acetone to see if it disolves. If it does you should be able to soak it out of the tanks. Some liners will, some won't.

Failed liners are bastards and I've heard many horror stories ..... often involving redkote.....

I'd be considering Por15.....
So por15 is a better liner then?
It's the best. I have two tanks lined with it. The first about 13 years ago. It's still good.

The other about two years ago - using the rest of the first can from 11 years before.

This is my limited personal experience but I've researched liners pretty well.

Others can and will add their 2 cents.

Most complaints of failed liners I've see have been ...... {drum roll} .... in first place - kreem. Runner up - redkote.
I'm interested in how you expect to get the rocks back out of the tank when you are done.

FWIW, I've heard that using a length of chain works as well as anything else but is much easier to remove.
Steel BBs or nuts can be removed with a magnet, along with loose rust flakes.
I figured if I shake the tank enough and rinse enough they'll come out. I was just going off what I've read. Hopefully it won't be too bad.
I had something into a tank that a magnet wouldn't pick up once and it took a lot of shaking to get it close enough to the filler to grab. Good luck with rocks.

That made me smile too much.


@ChrisDiehl Lowes carries muriatic acid in the cleaning aisle. Worked far better than vinegar if you end up with actual rust to remove, and maybe rocks too :)

Shop Vac?

Second the shopvac , hopefully he used small rocks! To clean tanks I take a spray paint can lid drill a hole for a piece of 3/4 inch tubing and stick it on the hose of the shopvac. I have used Por 15 on three tanks one is 11 years old , two points make sure tank is drier than dry, before putting in the coating and it dont stick to other coatings. Por 15 does make an excellent stripper , and the only one that will take Por15 off, cheers
The shopvac doesn’t have to actually vacuum the rocks, just grip them for removal, as a smallish vac tube will be needed.

Like a lousy claw game that you play half drunk with an eye patch and the prizes are rocks 😆

🤣🤣🤣not exactly what I was going for but that's a great back up plan
On the other hand if you used a chain you'd only need to snag it with a bent wire and you have the whole thing.
I too have seen disasters with tank coatings in the almost 40 years in the bike biz. Most...are due to poor prep work, or scrimping on the application times, etc. After fooling with 2 and 3 part coatings I decided to try single step RedKote after it was highly recommended. It has performed flawlessly in the TW-200 tank I ride weekly for about 12 years. YRMV. My only use of it so far, but I only used 1/4 of the can so passed it on down the line to other users. Have not heard any bad results from them. I will say it took 2 to 3 times longer to cure than the estimated time on label, but heat and humidity vary so much.
