Anyone Ever Use POR 15?

[Cyclejohn]

I bought my 97 Tourer back in the summer and went about the business of updating the maintenance on it. In the process I pulled the fenders off and on the underside of both was heavy rust and scale. I wirewheeled the front and degreased, primed, and painted. The rear wheel is much worse. I have no experience with this POR 15 but a friend suggested I try it. Does anyone have experience with it? Should I use it or just do the rear fender the same way I did the front? The paint on the top sides still looks like new. Thanks in advance for any help.     John

I used it to coat the inside of a gas tank on a 1976 Goldwing and it worked great.
Preparation is the key. It took me two weeks to get the tank clean and the metal free of all rust. It's still working great after 2 years.

It works well if you get all the loose flaking rust off first, you do not have to get to bare clean metal, just get the crud off.
I have used it on many old car and truck frames, it holds up for years if you prep it properly.

I just refinished my Utility Trailer with it this year... ground the loose stuff off, wiped it down with thinner and brushed it on.  Goes on great and covers well with a nice hard coat.  Make sure the wind is NIL and no dust around before you use it.  Use in a WELL VENTILATED area....   If the POR15 area is to be exposed to sunlight, put a top coat on it or the UV Rays will make it dull in short order.  I will have to touch up in the spring, with a top coat. 

POR15 about 50 bucks a pint as I recall  Kinda pricey.

Bought a supposedly "great shape" I/S tank off the Classifieds here last year...was lined with Kreem, and a poor job at that. As a previous poster stated: About 2 weeks worth of prep with the POR chemicals got the tank clean enough inside for the sealer to be poured in. Great product, I might add - sealed my tank right up and you'll have to dynamite the stuff to get it back off. I understand that Harley uses this or a similar product during their tank-fabrication process, and it holds up well.

Perhaps for the fenders, a spray on bed liner may work well.I believe you can get at many auto parts stores.

I think that I would take the worst of the rust off with a wire wheel and then coat the remaining rust with a rust-killer available at auto paint supply stores.  The one I have is called Rust-Mort.  I am sure that there are others that are just as effective by a different name.  Then two thin coats of bed liner from a spray can should protect the surface and quieten the road noises that are sometimes amplified by fender vibrations...JTL

Rusteco also works good.

Avoid the bedliner approach. All it's going to do is to provide a place for oxidation to keep occurring. If you get a pinhole through the other side and subsequent water ingress, the process will accelerate. The rust needs to be chemically neutralized then stopped by virtue of a metal sealer - NOT a paint or coating.
