gas tank question
tank on the new-to-me bike is a pale yellow inside. Is that a gas tank sealer coating or something else? I cant seem to wipe it off by sticking my finger down in and rubbing it. Seems to be pretty even but havent stuck a camera down there yet...

It's probably a Creem liquid tank liner. They can be OK when installed correctly or horrible if not. If it starts to peel and separate it will be hours if piddly poking and pulling. Large pieces can break off into fragments if you can see the outlet at the petcock is the area clear of sediment and junk ? If there is a screen, is it clean ?

Probably a Creme coating. If done correctly, then it works well. If not...well. it will provide many evenings of entertainment.

1993 ultra classic tour glide.
any easy or reliable way to remove it or prevent issues? I can probably get pics of the tank soon, just brought bike home last night and it is still in the trailer.

If it's Kreem tank liner and it's starting to turn colors it's only a matter of time before it starts lifting and the nightmare begins. Better think about getting it removed and replaced with an epoxy liner that'll last forever.

I hate creem...It always seem to fail even when properly applied. I agree a true 2-part epoxy is the answer in a properly prepped tank and I agree proper prep is the key.
IMO, just keep an eye on it. Anything chemical that is used to remove it will damage your paint. If it takes pulling the fuel screen in the tank every once in awhile, that is better than the alternative. If your not dealing with original paint, then that is a different ball game.
The factory coating in my 1994 was gray in color. I say was because that began to peal a few years ago, I had good luck getting the stuff out by using a long handled brush and a long copper tubing (1/4 inch copper tubing) connected to an air nozzle and blasting all the loose stuff out with compressed air. That is of course after removing draining and letting the inside of the tank be dry of residual fuel.
Again, I say leave alone and watch it. I have unlined tanks from the 1960's and 1970's with no rust. As long as you keep it full with good fuel in there (no ethanol during storage), no rusting will occur.

I stuck a camera down in there. It is not peeling but it does look like there is a little rust but just a couple spots nothing real bad. does not look to be peeling yet. I may paint the bike next winter if I like it and decide to keep it. That would be a good time to redo the tank. thanks
