Help needed on ply box in tinny

[ozynorts]

Hey gang, I have made a ply box for the tinny and am wondering what the best option is for waterproofing it is? The box has a built in esky and two storage boxes on either side of the esky. At this stage the box is a working template. At this stage I am thinking either 1) building a box in ali. 2) bouilding a box in ply and glassing it. 3) building a box in ply and coating it in something?
I don't have tools to bend ali. I don't have the skills to do a good job with glass. Help please!!

glassing it is not all that hard and can be sanded them some
flowcoat applied to make it look pretty.

otherwise use some epoxy paint

is it marine ply? if so, just painting should do the job and will keep the weight down although you will need to glass the esky part of it.

Have a crack at glassing it. Its not hard to do. As said before , the flowcoat covers most of the rough bits

a hand doing it

I did one for my tinny years ago and used pond or aquarium paint on the inner surface of marine ply. Got all the supplies from Bunnings
( minimal skill available for construction )
Absolutely waterproof, incorporated a drain and hose to a skin fitting and left it in place.
Have to say that the ply didnt insulate that well.

At this stage it is made of structural ply but as it is a working template I will be making another box and that is when I can change the timber. The ply was some older stuff I had lying around and used it to make the box. I didn't want to buy good timber and then get it wrong so have made this one. It works well so that's why I am trying to get an idea on what to do about the next one.
