Paint Your Air Vents
Paint is absolutely magical! It’s the easiest way to make anything in your house look brand new no matter how old it is. In this example, the OP wanted to give their old air vents a makeover. So, they whipped out a can of metallic spray paint and got right to it.
Just use an old newspaper so the paint doesn’t stick to spots outside the vent. Apply one coat, let it dry and then repeat with a second coat. In some cases, you may even need a third coat. As you can see from the “Before” and “After” shots, the results are amazing.
