DIY small radiator Shroud

that is looking GREAT! The woven glass cloth is much stronger than the chop mat BUT, as you said, it does not conform near as well to compound angles and curves. The mat us much easier to work with and as you saturate it with resin and work it with the brush, you can actually get it to "stretch" around those compound shapes pretty well. I bought a "roll end" from a local shop a long time ago and it has lasted forever. It was about 12-14" wide and the roll was probably 12" thick.. no idea how many linear feet were on it, it is still pretty big!
