To "The Pros" this might seem like a stupid question, but what is a nifty way to pour dope from a pint or quart can into a paint jar without making a mess and wasting a bunch of the spendy stuff? I've seen those plastic jobbies that snap onto the edge of a can to make a pour spout, but they just don't stay on a quart or pint can. Now I don't consider myself a "Messy Marvin" by any means, but no matter what I've tried I always seem to end up wasting more dope than I'd like just having to wipe off what fills up around the lip and/or runs down the outside of the can. It's especially frustrating when all you want to do is fill up an airbrush jar, but by the time you're done you've wasted half that amount.
 
 Any tips, tricks or photos will be appreciated...

What Don says is a pretty clean solution, I do it myself
I also tend to make a funnel on the edge of the can with masking tape because I detest the dribble that invariably finds its way on the part of the label with the color name.
Just a few pieces of tape covering the channel, then form the overhang into a trough. I typically trim the tape off the inside of the can so it pours better.

Being a real miser when it comes to dope, I use a set of aluminum measuring spoons to dip the dope out of the can and put it into the mixing jar. I then add thinner to the dope and stir it in with the mixing spoon, which pretty much cleans off the spoon. Then finish by wiping of the spoon with a paper towel with just a bit of thinner on it. When the can of dope gets down to about half empty, I start pouring it from the can, and use my brush to clean the dope out of the groove in the top of the can, wiping the dope off of the brush back into the can. This kind of evolved from my old R/C days of mixing K&B Superpoxy and measuring the paint and catalyst.

 Russ,

 Just noticed your tag line below, Risky Business, as in the old Reno Mustang?

 Ahh yes, I'm finally painting on my Shark 402 and I've now discovered that the 'ol "Hole In The Rim" trick works pretty swell.   Glad I asked, I would have never thought of it.

 Thanks!!!

Punching holes in the rim of the can works well.  But...make sure you've got a good grip on the can before you do it!  It will tip over and man, what a mess.  I now have my wife hold the can and I do the punching.
