Review on 🎨 Tight-n-Up Canvas Retensioner Spray: Unlocking the Artist's Masterpiece, 4-Ounce by Karla Richter

So it's ok. It's not too surprising or anything, but it's ok if you're looking at a little ripple and stretching the canvas again isn't worth the hassle. It's like a last resort. First, this thing smells disgusting. It has a distinct odor of cat urine. No one knows what's inside, but the smell will dissipate as it dries, so at least it's there. Secondly, after the first use, the spray pump is hopelessly clogged. Do yourself a favor and buy a stain/tint brush from the barber and use it to lightly brush the foul smelling cat pee onto the back of your canvas and then let it dry overnight. You'll get an even application and won't ruin your good brushes. But seriously? Before you mess around with this nonsense, just try out a few subframes. They are incredibly easy to use and take no time to dry.
