fillin up yesterday and see this floating in the tank. Pretty sure it's from where the painter did a terrible prep job, but wanna make sure it's not the tank lining.

 

Tank lining is pretty thick, that looks like paint from masking tape to me.

 

You mention bad paint prep...

So, you just had the tank painted? Take a flash light and look into the tank, to see if there is more in there. You should be able to see if the liner is coming away from the tank also. What you have there, looks like more than I would think could be unintentionally lost on new paint job...

 

Agreed. Use a dental type mirror that you can tilt to see around in the tank.

What year is your bike?? '99-'07? Yes that's the liner, had to do mine on my '03 Bagger. Unfortunately I think my Softail is next. = (
If you look in there you'll see it bubbling, if you do it yourself use the POR 15 kit. Best out there.

 

bike is a 2000.... tank's off an 02. Surprised to be having liner problems already. POR-15 makes a tank lining kit... good to know. Ppreciate it.
