Random Wrench Tip #3: Easier spray painting

If you're like us and need to the good ol' spray cans once in a while, you know what a pain it is to achieve a decent spray pattern from the cans.  This is especially true when it is cold outside.  Even if you constantly shake the cans to mix the paint up, you still get some awful spray patterns.  One method to reduce the blotches and achieve a better spray pattern is to heat the cans above the ambient temperature. 

An easy way to do this is to take heat enough water to cover the cans if they are placed in a small tub or container.  The water can be heated to about 110-120 degrees, and then place the cans in there for about 15-20 minutes.  Once you remove the cans, the spray pattern should be better and a bit more even.  As you use the can, it will cool down, but you can swap it for a warmer can and put the old one back in the water to reheat it. 

Note:  Take care not to overheat the cans as they may leak or explode, which would require you to clean up a mess!  Also, don't heat the cans over an open heat source, as they may explode.  Only use the water bath.
