New steel tank

Should a new steel tank be treated inside? If so what is the best method, Kreem, Red-Kote? A local radiator shop will do it but they want a lot of money.
Thanks,

If you are speaking of the Pakastani made replacements, I believe I would line the tank for peace of mind. I would not use Kreem.

I have used RedKote, Caswell epoxy, and POR-15 with good results on steel tanks. This is an easy do-it-youself job on a new tank. You should be able to clean and line it for $35-50 depending on what you use and how you prepare it. Preparation is the key.

A friend of mine coated his Commando tank when he did a frame-off resto with POR-15 . That was 15 years ago and it still looks like it did when he first put it in . I have a composite tank on my Ducati track bike . It never leaked , but fumes would seep through and cause the paint to bubble up . I talked to the POR-15 guys and they said that while they don't recommend it for that application , that they had heard of it being used succcessfully . I tried it and it worked great . I can't say for sure but I think it's what Ross Thompson uses to coat his tanks . There may be something else out there that's better , but I'm a creature of habit and tend to stick with stuff that's been proven to me .
Three of my 6 motorcycle tanks have POR-15 in them now , one is in work and I plan to get around to the other 2 eventually .

I line everything I have to prevent leakage and rust. I've never used Creme due to the warnings.
Eastwood has some good stuff as do several other folks.

hello Just coated my tank with KBS coatings 3 step system cleaner , rust cleaner and coating came out like brand new . Price was about 40.00 to do 2 -. 5 gal. tanks. I was surpised how clean it came after the the 2nd step the rust cleaner. M.C.

I used Bill Hirsch tank liner inside my fiberglass Norton tank and it's held up well for some two years now.

I've got the KBS lining on a couple of bikes and it seems to do a good job.
One Goldwing and one Chang, they were good to deal with on the web too. I like the fact that the KBS is silver so you can easily see when it is coated.

Whats wrong with Kreem ?

why treat a new steel tank? Just check it to make sure its tight.

If Creme is improperly applied it can come off in chunks and block the pickup. My current Norton has had someone do this and it will truly be a pain removing the remained of the Creme. I have chipped some away but an hour job has turned into a project that will become several hours.
And as to why treat a new tank, the reason is that new tanks become old tanks after a while. If you are going to put it together and sell it next week don't bother.
If you plan on keeping it long term and treat it the inside will look new in thirty years. There are ways to avoid treating the tank and still keeping it pretty good, like add Marvel Mystery Oil every few fill ups, but they are all a bit of trouble and I bet the expense adds up after a while.
The other issue on treating a new tank would be that substandard reproductions might just have a pinhole that can ruin a nice paint job, I've had this happen twice. The first time was years ago on a replacement Commando tank I did not treat and spent all winter painting.
The second time was my fault as I treated the tank but not the gas guage fitting. Luckily this is under the seat on that bike and I don't think it will show but it bugs me.
