Super coverite is the best!! Well worth the money. You can't wrinkle it!! It works best with high heat. It does not sag. It was taken off the market due to the chemical process making it producing too much waste. Glad to see it back. Coverite 21st Century Fabric is no comparison. It is way too heat sensitive and will pull away from corners if put on too hot. If you want colored fabric go with Balsa USA Solartex and give it a clear coat when you are done. This stuff is great to work with. Good luck
