Hi!

I'm building another iceboat this year and i intended to use a foam core and put fiberglass on it.

my questions: Is there anything you have to put on top of the foam before putting the fiberglass and the epoxy? (filler??? what kind)

I have shaped and sanded the foam but there is still some joint and cracks.
what can i use to fill those cracks?

How many layers of fiber is necessary?

any helpful information for me ?

thanks a lot.

I think so, check out this page from David Woodward's iceflyer http://www.davidwoodward.com/iceflyer/filler.htm

Have you looked at Dave Woodwards site: http://www.davidwoodward.com/iceflyer/final.htm

He built a glass and styrofoam boat and his site has a lot of details on how he did it.

Good luck on your project.

Roger

Thanks ! That's exactly what i was looking for.

Bye

Im not sure if this will be helpful at all since you may be experimenting but this link has some side by side pictures of a classic next to the glass boat.
