I've used POR 15 for several years with excellent results, and yes it is expensive. There are several ways I cut costs while not sanctioned by the manufacturer have worked for me.
I use naphtha for thinner in POR 15, stinks and needs a lot of ventilation. I do use their Marine cleaner for degreasing, but neutralize it with phosphoric acid cleaner available at home suppliers for cleaning floors and grout removal.
Spray equipment can be cleaned successfully with acetone,lacquer thinner, or MEK.
It can be top coated with regular primer if the surface is sanded or roughed up so it can get a grip. Their primer just saves sanding. POR 15 is good for filling minor surface defects as it is fairly thick and can be sanded to hide defects. I've also used their body fillers, they don't seem to let moisture draw through like the polyester fillers. Metal rusted to pin holes can be reinforced by backing it up with fiber glass on the back using POR 15 like resin.
I always wear latex gloves when using POR 15 because it won't come off if it dries on you hands. Also wear clothes you don't mind ruining because it won't come out of cloth.
And always put plastic over the can before closing, I use shopping bags, or it will weld the can closed.
My 2 cents worth.

Well, I have to jump in here because I have used POR-15.<br>POR-15 is ultraviolet sensitive. If you do not top coat it, it will fade to<br>a shade similar to old black CARC paint, sort of a grayish whitish black. If<br>you have never seen faded CARC, sorry, I cannot explain the color any better<br>than that.<br>POR-15 does stick very well to LIGHTLY rusted surfaces. POR-15 sticks to<br>skin and clothing FOREVER.<br>The pro about POR-15 is that it lasts forever, is superb prevention and will<br>even take hammer blows.<br>The con's are also many. The POR-15 company recommends using their<br>proprietary metal prep chemical, (a phosphoric acid mixture), they also<br>advertise that nothing will stick to POR-15 except their proprietary primer<br>coat. Their proprietary primer can only be thinned with their proprietary<br>thinner. Which you can then topcoat with their proprietary topcoats. They do<br>allow that other paints will stick to their primer.<br>All of these proprietary
chemicals and coatings are, naturally, expensive.<br>Having said all of these negative things, here is the bottom line.<br>I have used all of their products on my projects and they are so superior to<br>anything else I have used that I am a multiple repeat customer. That is<br>despite the high cost.<br>Yes, you can spray them, but you will have to immediately clean your gun<br>(drum roll.... wait for it.....) with their proprietary thinner.<br>No, I don't sell the stuff and don't have stock in the company.<br>-Sarge<br><br>P.S.

It's along the lines of POR-15. Now maybe they've chnaged over the years<br>but I<br> was warned many years ago that POR-15 in ultraviolet sensitive and needs<br>to be<br> topcoated. I'm not overly particular about the texture of the inside of<br>the<br> frame but I only want to do this once.
