Has anyone tested/used this stuff: Por-15

Its supposed to a "better than epoxy" sealant for metal in a humid or wet environment. I just wrote to the manufacturer to ask if they've tested in a reef environment, but was wondering if anyone else has tried it?

ive used it for the frame of my volkswagon bug, it worked great but the only thing wrong with it is that it breaks down in light so you would need to cover it with a coat of paint.

This is great!! I use it in car restoration and race car fabrication. The big seller for me was that you can brush it on and the finish will not have brush strokes of any kind. Pricey but worth it for me.

I just got a reply from the manufacturer that its not FDA approved, so they don't suggest using it in a life-cycle environment. Perhaps further coated with food safe expoy....

Whats your application??

I believe several people have used it for painting steel stands. Though not FDA approved, I would think using it in this was would be just fine.

If your thinking of sealing a tank with it, I would go with a more standard epoxy system.

it doesnt break down as far as i know, it only turns cloudy with exposure to uv. fda testing costs compaines money, so if its intended application doesnt require it, they will not pay for the approval/testing.

I'm going to build a steel frame large tank, and was considering this instead of 6x $$ in going stainless. Since the big tank is 2 years away, I just ordered enough to make a test tank, 2"x2"x2" with a mild steel frame. I'll coat it and run it offline with salt for a while to see how it holds up. I'm only reallt worried abotu the top rim of the tank, where it will bo closest to the water and lights.

This company brags a lot, but lacks technical data.

If the material is flexible … then they should list their % of elongation wouldn’t ya think?

If their material is “rock-hard” as they say then this refutes their claim to flexibility wouldn’t you say?

This sounds just like another epoxy to me. Actually they don’t even say what ‘type of material’ it is to begin with. Is it a polyurea, polyurethane, epoxy, acrylic, etc…?

randy, i understand where your comming from, but this stuff truly works wonders. its not some fly by night company looking to make a fast buck, they have been around for some time and used by the professional resotoration companies in my area.

We use it in our shop on resto's and if following the directions it is a wonderful product. Any seam that we redo on panel work this is coated on both sides before we progress to filling or smoothing any seams. We have never had a seam bubble or come back for any reason. It has a ceramic additive in it and when done properly is like a liquid powder coating. Coat it let it cure hammer it and it will bend but not flake off.

I put two coats on it for my 300 gallon stand and have no worries that it will last for me.

I believe if you look on thier web site someone told me they have a marine product now. I did not look but if this is the case thier reputation for what they have made so far would sell me on thier new product in a instant.

We go through about 5 gallons a year on frames, panel repair, pinhole fixes on metal sheet and would not think about using anything else.

Hope this helps.
