I've been wondering about this for a while, I didn't know people complained so much about the shelf life... It seems that there are some decent tips and tricks for stretching that life out.
For those of you who don't already know, POR-15 is a rust inhibitor, and has been very positively reviewed everywhere I've looked. Research proper application and storage techniques before using, as it's pretty hardy stuff. Don't inhale it, either.
POR 15 is a great product, I've used it numerous times. I've actually converted a friend over to POR15 (Unfortunately they don't pay for advertising )
Only bad reviews are by people who misused it and it peeled off on them.
What I do is I put some saran wrap between lid and a can and then tap it with hammer so it seal very well. Also keep area between lid and a can clean.

I've found 2 spots of rust on my '92 to date, 1 in the door seal of my passenger door(I have a replacement door already, because of the other damage), and a spot in the hatch that I'll be cutting out and replacing.
I've got a lot of rattles in the rear end that make my ears bleed. (Or the high volume I play my stereo at)
I'm planning on putting a layer of the rust inhibitor spray down, then filling the less used pillars, panels and nooks with great stuff expanding foam.

This stuff might be used on my floorboards though. I am planning on ripping out the carpet and checking if the ninja leak in my roof has done any damage to the floorboards. Plus soundproofing.
What is the average time that POR-15 takes before it becomes useless?
Wings on an MX3? What are you thinking?

POR-15 has isocyanates and these chemicals are considered carcinogenic (causes cancer) always wear a niosh approved mask and if spraying the product I recommend wearing some thing like tyvek coveralls as the product can be absorbed through the skin and the eyes. Never let this product come in contact with your skin. My 5 cents.
