When there is only a little bit of paint left in your can, but you want to keep it fresh for that small touch-up down the road, Ron offers this great tip.
Ron took a sports water bottle, unscrewed the cap and set the base inside a roll of tape to steady it.
Next, he inserted a funnel in the top of the bottle, and poured in the remaining paint that was left in the can.
Before he replaced the cap, he dropped in three or four marbles.
When was time to use the paint, all he'd have to do is give the bottle a good shake and let the marbles do all the agitating.
Then he opened the top and poured out just the amount he needed for that touch-up job.
