Hey GPW - I’m just brand new in here. Been trying to learn PMF.
Not ready for a camper yet - but just a few projects to get the feel for it.
So - question re: fabric. I wondered if Fiberglass will work well ( or Kevlar) with Titebond II.
I have a Composites guy nearby - and I’m sure he would slice me off a few yards at his cost.
So I have a smaller project to start with - Tonneau cover for pickup. PMF over XPS
(or, I do have some EPS on hand, but not sure if that will work out ok ??)
So perhaps I just need 80 Sq. Ft ( 40 top, 40 bottom.)
My goal is Light / Thin / Strong.
So I don’t mind spending a few extra bucks on, say, glass vs canvas… if it would be lighter weight.
But I would love to confirm that it will glue up nicely.
Then I would paint; or try MonstaLiner or equiv, as per the big write-up by Tony L (?)
Just looking for direction here.
You seem knowledgeable on this - perhaps you can give me some input. Really appreciate. Thanks.
