Another tip that works with any kind of paint. Punch a few holes into the recess of the can top. When you pour the paint it drains back in making it easier to get the top off next time. The plastice wrap also wont stick as bad either.

I had the same problem, -if you dont get a good seal, the top will harden, but below will stay liquid. If this happens, be carefull when you cut through the top so you dont spray your self with it!!
-good idea on the new empty paint cans, by the 3rd time or so I use one of the quart cans, the top is totalled from using a rubber mallet to re-close it.. -i guess decanting it immediatly into a metal cup and sealing the origional container would be a good idea, so that no residue gets onto the top... |

I am not sure how well it is going to work, but I bought a regular 1 gallon paint can at my local hardware store and put my 1 qt POR-15 can inside that. Since I pour out of the smaller can, the big can doesn't get anything on the lip.
Not sure how long this will work, as there is a lot more air that the POR-15 sees, but we'll see. Not a bad idea to evacuate the can with duster, or maybe even some welding gas that might be handy. -Tony |

I've had pretty good luck using cap plugs (size #18) for the little cans. The sides of the cap plug is tapered and wants to pop back out, but the suction/vacuum caused by pushing the cap into the can keeps it in. POR doesn't stick to the caps so removal is easy, not sure what size the quart can would be, but I'm pretty sure they'd work just as well.
Refrigeration (not freezing) would help I would think, but the guy's at POR told me the shelf-life is only about a year, even for unopened cans (had some new ones cure on me (IMG:http://www.914world.com/bbs2/html/emoticons/dry.gif) , they replaced them free of charge (IMG:http://www.914world.com/bbs2/html/emoticons/huh.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif) ) Sorry about the focus of the pic, forgot to press the macro button (IMG:http://www.914world.com/bbs2/html/emoticons/slap.gif) Attached image(s)

A painter friend says thin it with Lacquer Thinner rather than buying their over-price thinner.

do the small cans only have a shelf life of a year? I wonder why my quart can has lasted so long . . .

IIRC, the moisture is actually a catalyst that triggers the linking of the urethanes. Since a single H2O molecule in the can will _eventually_ make the whole mess solidify, anything you do is just delaying the inevitable. |

Keep it under dry nitrogen. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)
Not you Aaron, the POR-15. |
