Well even thou this thread is about weight, we are talking about skins. The fiberglass skin I used is .3 lbs per sq ft, while that is cloth and gel coat its probably pretty close to what you get if you did a hand layup and filled the weave and painted it.
As for puncture resistance a premade fiberglass is probably the best, followed by aluminum skin, followed by a woody, followed by PMF and hand laid glass. But then we get in to each one a little further, fiberglass is pretty dent resistant and not too bad to repair. Aluminum would dent pretty easy, hard to punch a hole but dent easy, and not easy to fix and look decent. A woody I would think dents, but not super obvious, and puncture not super easy, but depending on how its built can be easy or hard to repair. PMF and hand laid glass should be pretty good at dent resistance its all whats under it denting, not super hard to punch a hole, and not too bad to repair depending on how it was finished in the first place.
I would also guess PMF weighs more than premade skins, and hand laid glass. Aluminum is probably pretty light too. If I had to guess PMF maybe the heaviest skin once complete.
