POR-15 POR-15 Logo

I saw this stuff demonstrated at AutoRama 2000, here in Ottawa.  To look at it, it seems to be nothing more than black paint.  The POR-15 booth had a demonstration piece, an old battery tray.  One half was left in its original condition, rusted, pitted and dirty.  The other half was treated with the POR-15 Gloss Black paint.  I tried to dig my finger nails into the paint, just to see how strong it was.  There was no give.  There was a hammer at the display.  I picked it up and gave the battery tray a good, hard whack.  The paint didn't even mar.  This is strong stuff!  I immediately thought of uses for a product like this.  The floor pan, under the carpet, of my car.  Inside the fender wells on both my car and bike and anything else that is rusting.  I took a business card from the guy behind the booth and stored it away in my wallet for safe keeping.

Before using POR-15
After POR-15


I didn't actually buy some of the POR-15 until recently.  It's winter time now and my bike is in about 200 pieces in my garage.  I may as well take the time to coat the underneath of my fenders and fuel tank.  I looked on the POR-15 website for the products available.  There's a lot of them!  But I only needed the basic, gloss black, I saw at the car show.  To order the stuff I found a 1-800 number on the Canadian distributor's website. www.por15canada.com  You can also try www.porcan.com

In about 5 working days I had my pint can of POR-15 and was itching to get going.  The only preparation I performed on the pieces was to clean them with a degreaser and dry the moisture from them.  POR-15 doesn't take well to ANY moisture.  I baked them in an oven for about 30 minutes at 60°C.  Just a word of caution, I have access to an industrial environment chamber with proper ventilation.  I wouldn't recommend you putting motorcycle parts in your home oven, especially a fuel tank!  Using a hair dryer can work just as well.  Keep in mind that gasoline fumes will explode if exposed to a spark.  Be sure your tank is perfectly clean before attempting to use any source of spark around it!

Before you start to paint *Be sure to read ALL of the directions on the can.  They're there for a reason.* Mask off all of the edges and grommet holes with painters masking tape and screw in any screws that you may have taken out when removing the fender.  Be sure the screws are flush with the underside of the fender, otherwise you won't be able to remove them again.  We're putting them in there to prevent any of the paint from getting into the threads.  Pour out a small amount of POR-15 into a container and reseal the can with a piece of plastic in between the lid and the can.  Use a small paint brush to cover all of the surfaces needed to be sealed.  Just paint right over the rust.

Just as a note, when I was finished painting, I tried to wash the paint brush with some Varsol.  I had to throw the brush out because I couldn't clean it.  POR-15 doesn't mix with petroleum or water based cleaners.  It's weird stuff.  I think it's Epoxy based or mabey Cyano-Acrylate (super glue) based.

After 6 hours, the paint was still wet.  After 24 hours the paint had dried enough to touch.  After 48 hours, the paint was ROCK HARD!  Of course, no matter how careful I was, I still managed to get POR-15 on my beautiful tank.  Fortunately, this paint needs a rough surface to adhere to.  Peeling or scraping the dried POR-15 from my highly polished tank and fenders was quite easy.  Getting it off of a rough surface is another story though.  It's there for life!  I did find that the POR-15 had a hard time adhering to portions of my front fender though.  I think this is due to the lack of rust.  I would have had to treat the underside of my front fender with METAL READY, another POR-15 product.  It's an etching solution that would prepare the metal and leave a rough surface.  At any rate, I'm pleased with the results.

So there you go.  My experience with POR-15.  I recommend this product.  I'll add more to this story after the next summer just to let you know how it's holding up.

(2 years later) I just inspected the paint. It's still in perfect condition. It looks like rocks just don't bother it. The rust? There's still none. This paint has sealed the previously rusted areas from any moisture and air. It cannot rust anymore.

Notice there's not a lot of rust on my front fender? I should have used some Metal Ready to prepare the surface.

I used a Gloss paint, so it still looks wet.
