I just recently picked up a 80 GS850 that has been sitting for a while and the tank is rusting inside. I've cleaned out a lot of the rust and i was wondering if i were to seal the tank with a liner would this work? or would it continue to rust?
 
i used kbs-coatings and plan to use it again on another bike. pretty easy to do also.

Hello again!

Hi Mr. GSJake,

I've posted a response to you in your original thread - Click here to see.

You could also find tons of information by using the Search Feature and searching the titles in the Tech section for "clean tank" or "rust tank".

Good luck with your tank. Now let's see some pictures of your bike! :-D

Thank you for your indulgence,

I went through hell and back getting my 550 tank properly cleaned and sealed. Much of the problem was my own making since my first sealer attempt failed due to moisture inside the tank. Live and learn.

Some of the things I learned are:
1) Figure out a way to completely seal both the petcock hole and the filler hole; I wound up fashioning bolt down rubber plugs which allowed vigorous agitation without risk of leakage. Tape is not good enough (I tried).

2) Get a bag of aquarium rocks and dump them in the tank during the phosphate wash phase. The phosphate will create a chalky residue on the metal and the rocks knock off the chalk as well as scrape the rust off. Nuts and bolts, or drywall screws, don’t work for crap (yes, I tried).

3) Give the phosphate enough time to remove the rust – may take a couple of days.

4) Swish around the phosphate/rocks solution in all directions to contact 100% of the surface area inside the tank. The top/bottom/sides are easy to hit by rotating the tank. The problem area is the upside down U-shape section that straddles the frame. You need to focus your agitation action to throw the rocks against that area of the tank to get it clean.

5) Make sure the tank is dry before applying the sealer, a hair dryer works well.

6) In my opinion you should use double the amount of sealer recommended - having extra sealer makes it easier to make sure all the surface area is coated. You can always pour off the excess.

7) The POR sealer is thin and runny. It dries fast so you need to swish it around promptly.

8) The Caswell epoxy is thick. You need to purchase the phosphate wash separate. They provide a goodly amount and recommend using half – I used the whole lot and poured off some. Even after pouring the excess off, a good bit will remain in the tank. My tank was noticeably heavier after the treatment.

Good luck.
