Tank was coated inside 15 years ago so I guess I can't expect much more. Now there are chunks of POR coming off and bits of rust. I can take it to a dealer again but I'm wondering where they send the tank to in the York/Toronto region. Dealer wants the commission so they are not saying and I'm thinking it might be faster if I could drop the tank off directly. I don't want to do it myself.
The way I read his post, the tank has been previously coated, and now the coating is flaking off.
To put anything NEW in there, he has to remove ALL the old coating. GOOD LUCK WITH THAT!
If I were OP I would venture out to Shannonville next weekend, to the VRRA Spring thing, and talk to Pat "I don't remember his last name" who you will find under the bleachers selling fibre glass parts. He is an expert on coatings such as this and he would have an answer on at least who to talk to.
... I'm a bit of a caveman. I'd just fill the thing up with Hydrochloric acid and let it sit for a while. No need to coat it after.

Sounds like the original POR treatment missed a prep step.
Restoring old tanks is a bit of an art, particularly if they have already been coated inside. I did this once -never again -- it wasn't worth it. The only way I coulkd find to remove POR is burning it off -- for this you need to uniformly heat the tank to about 1000F in an oven or BBQ Then you have to clean and prep the inside of the tank using electrolysis tank flowed by a vibrating or ultrasonic clean.
Now you can re-do the POR steps using metal prep and sealer and of course you will need to repaint (you probably burned off the paint too!
Better idea? Find a used tank and have it painted to match your bike.

I haven’t used them, but a while back I looked into places around the GTA that could seal a tank and these guys were recommended on another forum Gas Tank Exchange - We Do Gas Tank Repairs
I don't think that will work for a MC tank -- strong solvents will turn PU coatings like POR into a gummy mess that gets removed with a scraper or wire brush. Maybe car tank with a large access hole, can't see how you would do it with a MC tank.
