Tank Coating

[Case S2R]

For those that have coated the inside of a tank, what did you use? Caswell? POR-15? Something else?  And what were the results?

I am contemplating coating my new plastic tank in hopes that it does not expand so if you have any insight, I would appreciate it.

Thanks,
Case

I've used Kreeme, POR, and recently the Caswell.

Kreeme is absolute junk.

I prefer the POR. I've coated literally hundreds of steel tanks and never had a failure besides a carbon tank that split wide open at a seam.

I don't think the POR will work on a plastic tank though. It's a urethane product and those types of coatings generally won't stick to plastics without an adhesion promoter.

Caswell has claimed it's coating will stick to plastic. I think if you follow the instructions and rough up the inside as recommended it may be fine. The things I don't like about the Caswell coating is it is clear and difficult to determine coverage, and is so thick it is difficult to get the excess out.

I bought some Hirsch tank sealer for an old Suzuki tank.  I have not used it yet but I've read good things about it.

Kreeme is total junk.  I have to re-coat my tank (steel) and I am planning on using the KBS Coatings Kit.  Did a bunch of research, it was down to that or the POR kit...seems to be a lot of people on motorcycle forums that say both are great.  It might sound silly, but I like that the KBS is a bright silver in color (POR is black, if I remember right) - which, imho, looks better and makes it easier to check out the inside of the tank from time to time.

Ah, thanks!    Have you ever used the KBS Coatings stuff?

No I haven't.

I've had excellent results with the POR and haven't felt the need to explore.

I buy it from the same supplier I get all my other materials from so it's convenient.

The only way it could be better was if it was less money.

What is the price on the KBS?
