here is a couple shots of the hood liner we built on my buddy's squarenose. It was a couple layers of thin stuff. 8oz weave maybe. I put a few strips of biax in there afterwards to toughen in up cause it felt a bit flexy to me after it cured. He doesn't beat on his stuff that hard so I can't give it a bulletproof rating but its very light(10-12 pounds). Lighter than my WDK diablo hood or my Tom21 hood and it was custom made.
Speaking of custom made, I will never try and build a hood again. we put so many hours into that hood just to make it what it is(nothing special) and I could go buy a hood for 4-500 bucks. The day we finished building that hood I vowed to never try it again. 4-500 bucks is cheap for a hood when someone else builds it and makes it look nice.
anyways here are some pics. Hood liner and finished project pics. Its still a 90 square, just looks different. Handles the same.
