Por15.....fyi
Did you ever put the lid back on a can of POR15 and then try to remove it a few days later? Can't be done.
Drill a small hole in the lid near the edge and another in the side of the can near the top, opposite the hole in top. The top hole is a vent so you can pour from the side hole into another container. Plug both holes with sheet metal screws that fit tightly and seal. Give the can a shake to coat the screws inside to help seal and refrigerate for longer shelf life. Refrigeration not absolutely necessary but, NEVER EVER REMOVE THE LID OF POR15. It makes good glue.

Good suggestions.
POR15 is basically "Superglue" with pigment(i.e. it's an isocynate)
. Most paints harden by outgassing volatile components. POR15 does not harden by outgassing. POR15, like "superglue" hardens by absorbing atmospheric water vapor. Once POR15 is exposed to atmosperic water vapor it's going to start to harden. This is why there's a problem with putting a lid back on a can of the stuff.

I always use plastic wrap under the lid. The lid will come off again when you need to use it again. But the POR15 will still set up if you leave it on the shelf long enough. I have had a can set up while on the shelf before with the plastic wrap being used.

Well if you don't take off the lid you can't stir it... According to the instructions you shouldn't shake it because it leaves small bubbles in the paint that never escape/pop so it doesn't give as nice of a finished surface. (I've always stirred it so I can't vouch for whether that happens or not).
I take off the lid and pour whatever amount I need into a seperate container (shouldn't paint out of the can) then get the excess off the cap with a brush. To prevent the lid from sticking I use a piece of paper towel with a little laquer thinner to clean things up. Did my whole frame and then some and never had a problem doing it that way...

Same as you guys, I clean the lip & use some plastic wrap. Then I put the can in a zip lock back and get as much air out as possible.
Works so far, couple of cans are more than a year old.

I use a plastic kitchen measuring spoon to scoop out the paint into a separate smaller container since all my jobs have been fairly small. Then I cover the original can so it's not left open. My quart can is still about half full and about 8 yrs old. I noticed last summer it was starting to thicken up but was still usable.

I used the all in one special from the www.por15store.com
It was enough to do two coats of POR-15 and one top coat on my frame, control and trailing arms, and a few other pieces.

I bought mine from their web site. You can call them and they can tell you how much you might need and what else to prep the area you are going to paint. I just finished my fuel tank last night, and will start on my frame this weekend. The tank looks great, I used silver.
