everything you wanted to know about POR and were afraid to ask...
another friend on another board posted this link to his POR-15 FAQ... lots of good info there on this product and I know there is always a question or two about POR here on this board...
here's the link and thanks to John Blair at autox.team.net
Reading the part about storing the liquid reminded me of a product I once read about. I can't remember what it was called, but it was essentially a pressurized can of inert gas. You spray a little of it into your paint can before you seal it to displace the air in the can. It's supposed to keep the paint from skinning over, and make it last a lot longer.
I've also read about using propane for this same purpose. (Just remember, don't push the ignitor button on your torch!)
Using this method, I'm thinking you could probably store the POR 15 in its original can, instead of all those little jars.
I know this sounds weird but it worked for me, after opening and using POR15 I filled the half empty can up with marbles I got from the $1.00 store, enough to raise the level of the paint back up to the top, then placed a layer of saran wrap across the top the put the lid back on. Worked for me the 1/2 of can lasted from spring of 2006 until I needed it again last summer. Previously it dried up like a black brick in just a few months.
Article dated 2000. You can buy a couple different colors now and many auto paint stores stock POR-15. Saves your shipping cost. if your doing a clean frame really rough up the metal or it will not stick. Some are using it inside cab, under fenders, ect. If the sun shines on it, top coat paint over it. Paint brush works great, flows nicely. Have a great day,chuck
Its simpler not to open the can. Poke a hole in the top outer edge and right below the top edge opposite. Poor from the side hole. Cover with tape when done. Keep refrigerated and will last for many years. By not removing the cover moisture wont enter to cause it to cure out. I purchase in gallon quantities. Currently one particular can has been in use for 8 years and still good as when first acquired. Coverage is great. This stuff sprays out better than most paints. Its self leveling and fills well. It doesnt gum up gun, if you know what you are doing. Cleans up easier and with less solvent than most paints too. You do need an HVLP gun to shoot with tho.
I own a mobile sign business and have 28 signs that sit outside all year. And in the winter they get covered with salt spray from our great Ontario roads. I started using PRO-15 last year. I try to paint about 5-6 sign frames a year to stay ahead of the rust but I was losing the battle with paint that claims it stops rust. So far this spring the ones I painted last summer show know signs of rust coming back.Great product. Its going on my truck frame.
I would pick a spot on top of the frame that would be hidden (under bed/cab) lightly sand a masked off area example 3 x 4 inch. Paint on your top coat, let it dry, check to see if it holds without affecting the POR-15. Have a great day,chuck
Strange as it may sound, I've incorporated wine drinking into my POR-15 journeys!
I also poke the hole into the side of the can Vs opening it completely. But then I spray a small amount of nitrogen gas into it that I get in little cylinders at the local wine shop. They use them to fill the voids in opened wine bottless before putting the cork back (some systems actually have a needle to go through the cork) That way the fresh air, moisture and oxygen doesn't spoil the wine (some of which go for hundreds of dollars out here - no color changing cold lables). Nitrogen is inert and won't blow up in your face like propane if the next guy opening the can happens to have a ciggy in his mouth! WOW!
OK a little California Culture FTE style - tee hee!

Ummm.....never heard of that. When we open a bottle, we just throw the cork away!........Rod
The trick to using the Por 15 rust preventative paint is to use the 4 oz cans, depending on the size of the job that is, but one 4 oz can will go along way. The quart cans will dry up and if you can get the lid off again will be waisted. The 4 oz cans are about 10 bucks and if there is some left just press the top on and it will seal itself and I have found will last like that for several months. As far as painting over the Por15, if it is set up then you should rough it up and use their etching primer. I used the Por 15 on my 52 blasted frame and then put the Chassis Coat over it within 24 hours about 5 years ago and it has stayed on. The etching primer is something new and I have not tried it. Anyone in Ontario that needs Por 15 contact Crawford4@accel.net as he is a dealler here in Peterborough.
Good luck and wear rubber gloves or your wife won't go anywhere with you.
