I know this topic has come up before.

The bike is a '75 R90S. The inside coating on the gas tank is starting to peal up. Trying to decide what to reline with.
My consideration is what was "original". I've used POR-15 on other tanks and am happy with it, but don't know if I want to do it with this bike. Is Red-Kote BMW original, or did they use something else? Is it worth re-coating with whatever was original, or going to POR anyway?

Thanks,
Seth

use the POR15 its better than cream

I don't know if anyone has ever identified if the original is actually RedKote, but if not it is certainly something similar. Far as I know it responds to the same solvents.

RedKote is certainly more "original." POR-15 seems to be a much tougher product (important if sealing seams and pinholes is a major consideration). Go with whichever gives you the result that matters to you, but the most important thing is getting all the old stuff out before you use the new stuff.
