thanks again martno1fan. I know many modellers who just epoxy their hulls. However, I'm gonna apply 1 or 2 layers of the lightest fiberglass cloth I'll find just to make it extra strong and more waterproof. I just hope that the overall weight of the hull does not increase dramatically[]

I will post any other question that rises since you know the subject so well and you are willing to answer

Again thank you very much,

Orestis.

p.s. By the way your Banana Split looks great!!!
