Liquid clear is a tricky product. I like it under certain circumstances. It reacts badly ( or good depending on the need) with solvents. It will cause "runs" which I found out the hard way but caught it in time to lay the canvas flat to dry. You need a very, very, very ( did I mention very?) thin coat and even then, I would recommend it only where you need it. My first use of LC was a starscape where I had used gesso for the black background and cleared the entire canvas. Thats was "instructional" lol.. I've used it a few times since with better results.
