Peel ply

[SuperDrifter]

Of course smoothing, applying pressure, is needed when you are done building layers. But isn't peel ply an expensive version of heavy mill PVC? (it don't stick)

Define expensive it's $5.85 a yard at USCOMPOSITES.COm , that's for a 60 inch by 36 inch piece, how cheap do you need it to be ?

I quess my question was why, I've got pvc sheets everywhere. It's my grinding curtain. Home depot 10$ for 1m yards lol

Tougher question, What is the ideal core material (if any) of 2024 tech on a Jetski's upper hull. (S-glass version)

USCOMPOSITES. great supplier. Shipping $ sucks. Price generic 1708 glass fabric to chinese (prol the same supplier) AMZ. no ship$, 2 day. Epoxy and specialty only for USC!

Peel ply? I use nylon cloth. For core I would use dense PVC foam. Balsa is the most effecient but it will rot. Rohacell is expensive and looses half its strength when it gets wet. Nomex $$$$$.

Using peel ply as a final layer on a hand layup was probably the best advice 8ve been given doing glasswork. Removes air pockets, leaves a nice finish that reduces sanding by at least 50% as well as removes the blush left with the epoxy curing process that must be removed before any further work is done on the layup or part.
