Por 15 questions
Is Por 15 the product it claims to be? I am restoring a '42 1/2 ton on a limited budget ( no frame rotiserie, no powder coating, sand /bead blasting) I am willing to use my elbow grease to prep the frame/suspension.as much as possible. Is Por15 as durable as it claims. Thanks

A friend of mine used the Por 15 on his restoration and it is holding up real good. He did the same with the elbow grease, a lot safer than the sand blast, in my opinion anyway.
Stuff gets into just about everything, and is you don't remove the body, it will be there forever.
Its by no means a cheap paint or preserver by any means, but it does get the job done. Where you are Geographicaly you won't have a problem. Are you on the Pan Handle or the Eastern end?
Just curious as I usually travel there 2-3 times a year, have a few friends down there. Anyway hope this will help answer your question.

First off, welcome to FTE injunmark. 
I have used POR 15 for about 10 years, and have found it to be great. Just follow the directions that come on it, and you'll be fine. I have used it on frames and it holds up great. Makes sure the loose rust is off and prep it correctly and it'll hold tight. Brushing it on is easier than spraying it on, and you'll have much better control of it. Be careful of getting any air bubbles while painting. I have had some parts where there seemed to be some air in the paint, and it didn't go down real smooth, and those areas later started to lift a bit. But if you lay it down nice and smooth, you'll be happy with it.

A contrary opinion just to balance things out a little.
I painted the rusty wrought iron gee-daws bolted to the front of my mother's house 20 years ago with brush-on Rustoleum. Still looks really good.
I painted the running boards on my truck 15 years ago with Rustoleum. Still looks good.
My buddy painted his car trailer last year with POR 15, now completely oxydized wherever the sun has hit the paint. Looks worse than terrible.
POR 15 is extremely hard to take off or paint over a later date.
1 quart of Rustoleum, about $7.00
1 quart of POR 15, about $42.00
If the sun is going to shine on it, don't use POR 15!

POR 15 recommends top coating if exposed to the sun. It doesn't oxidize, it dulls, yellows, what ever you want to call it. POR 15 seals the surface, while Rustoleum is still porous. Again, follow the instructions and it's great.

injunmark, Go to this web site http://www.por15.com/ and read all about it. There is a place there to order a free catalog. You can purchase what they call a starter kit with some small samples of the different things to do part of your frame for about $16.50. That is what I did and I liked it so well I went back and bought a lot more. It seems to work. You have to coat over the por-15 with what they call Chassis Coat Black to protect it from the UV's of the sun. I ordered my paint directly from them. It took about 6 days to reach my doorstep.

Mark, I used the por-15 silver color so when I coated over that with the chassis coat black it made it easer to see where I had been. By the way you said you were in motorcycle groups, does your user name injunmark, mean your into Indian motorcycles? Just wondered

Hey someone else who likes to site scientific literature. The article above was published in the engineering journal "Industrial & Engineering Chemistry Vol. 42, No. 7: July 1950". Of course to me the weak link of siting this study is that it was published in 1950, you would have to assume that no further development of paints has occured since then for it to be valid. But just to be fair, I think that if you google "porosity of paints" you can see that it is one of the biggest research subjects of the paint industry (and continues to be a problem).
Sorry I still can't add anything to the debate, but it has been very informative so far.
Assuming that all that has been said is true, though, wouldn't it mean that Por15 is an inferior product still, since it would require continous touchup to keep the topcoat intact so that it doesn't breakdown?
Again though I have to continously touch up the rustolium on my trailer to keep the steel from being exposed, so I guess its a wash for the touch up idea (unless it is really hard to fixup the Por15 if you don't get the topcoat touched up quick enough.
