I have built 2 of these for my sons also but didn't fiberglass either of them, 1 is 1/4 plywood that I coaxed into a slight curve using boiling water and pressure. We painted that one with a brittish flag design.

The other one is 3/8" plywood and is much stiffer, I wasn't able to bend that one. We just painted it also.

Both have been used several times a year for 3 years and are in good shape. I don't see any reason to glass them.

We used a lot of surfboard wax for nonskid.

: This is a little off topic but I promised my son that I would make him a skin
: board with the leftover fiberglass and epoxy I have. A skim board is a
: piece of plywood shaped in a short thin surf board shape. You run along
: the ocean's edge throw the board in front of you in 1" deep water,
: jump on and slide for 25-50'. Great fun in the summer time as our beach
: has a long flat sandbar in front of it. Some questions related to building
: this.

: 1. He wants to paint a design on the top. Should I paint the plywood core
: first then fiberglass or will the paint prevent the glass from adheering
: properly. Jumping on these things create a lot of forces and I am
: concerned that the glass will delaminate. What type of paint would work
: best

: 2. Any recomondations on layup. I have a lot of 6oz cloth left over and
: didn't know if two layers top and bottom was overkill

: 3. I am using 1/4" plywood as the core and rounding over the edges with
: a round over bit. Any thought on how to glass the edges. I can't immagine
: that the cloth tape would lay flat in the front bending around an arc
: shape with a 1/4" edge.

: 4. What is the best way to get a non skid surface for the top. If you don't
: do a fill coat it would be non-skid but it might not hold up to sandy feet
: jumping on it.

: Thanks for the help any suggestions
