I'm not a big fan of super clear canopies. I like just a trace of tint so you can see the canopy. Sometimes you'll see a plane with a canopy so clear ,at a distance you cant even see it. That's why I do this.

Years ago I picked up this single burner hot plate at a Yard sale. I use it to keep the water temp high so the dye can do it's deed. You must heat the water!
