This product is GENIUS!! It’s a mini paint sprayer that is absolutely perfect for small projects, like this air return vent that I wanted to blend with the wall. If using latex paint, I found that you really have to thin it with water. I probably did a 50/50 ratio. The unit is finicky but it eventually worked. I had a backup canister in hand, which was helpful. The first one got very cold and had to warm up before I could use it again, so the second canister came in handy. This is a really great tool for small DIY projects where you don’t want to have brush strokes or pull out the large paint sprayer. LTKHome LTKOver40 LTKFindsUnder50
