It's worth it [when applied properly. It will last a long time but it's not the be-all/end-all of rust preventative. It will eventually (years...decades?)loose it's glimmer but no where as fast as the other products out there. It's still one of the best products for restos.

From what I've heard, it's not the easiest stuff to work with, very toxic, precautions need to be taken, and there are several steps in the process of application. But, the end results are supposed to be excellent, and last for a very, very, long time. I've also heard of one that's similar called "Zero-Rust" I think, and it's supposed to be easier to work with, and also has great results. Wish I could say I've used this stuff, but I always have looked for and bought cars that had solid pans to begin with so I didn't have to mess with that stuff. Good luck, and let us know your results...

Kubel Nick has nailed it - great stuff when applied properly. It's practically indestructible.
I don't find it difficult to work with, really, especially since you brush, rather than spray it on. I recently POR-15'ed all the front-end parts on my '71 Bus, and have been very pleased with the results.
What you have to understand going in is that you're not really doing this for looks. Granted, the glossy black finish looks great when you put it on, but it degrades in UV light, so unless you paint over it (which is an expensive, more difficult process), it will lose its color and sheen, though not its protection.
It really is best applied to bare metal that has been treated with the Metal-Ready product. If you paint it over paint or untreated metal, it is likely to simply peel off.

eastwood's corroless is a quality product as well (and cheaper). the two both work fine. much better than not alternatives.... letting the vehicle rust or paying to have all new metal welding in.

Compared to the traditional method of doing a chassis: sand blast, acid etch primer, epoxy primer, and enamel the POR15 is much easier to deal with. The only precautions I take are to wear a good vapor mask, gloves, and goggles. These are the minimum you would use for spraying all the above. Brushing on a single coat of POR15 is a heck of a lot cheaper, easier, and more environmentally friendly than doing all the old fashioned stuff, IMO.
I used it on my wheel wells, brushed right over the PPG urethane, just for chip protection. It's been on there three years with no sign of coming off. Maybe I'm lucky on that.
