the decks are solid glass and the headliner panel has been removed
so i could remove the deck hardware

The easiest way to stiffen the side decks based on your description
would be to loose fit a piece of foam, say 3/4" Divinycell, to the
underside of the deck, then remove it and glass all exposed foam
surfaces with a couple of layers of 10 oz cloth.

After it cures, install it using some 5200 adhesive.

Allow the 5200 to cure at least a week, then remount all the deck
hardware you had to remove to fit the foam in the first place.

The 5200 will not be as strong as if the foam was glassed directly to
the bottom of the side deck; however, it should be strong enough and it
eliminates trying to lay glass overhead.

Lew that sounds like a good idea. should i glass both sides of the foam? i think i might use my left over west system epoxy thickend with 404 high density filler. im not sure ill have to measure but 3/4 will probably be to thick because of the amount of space between the headliner and deck plus i have to fit bolts in the area. the only deck hardware is a genoa track which i might move closer to the hull to deck joint overlap which is 7-8 inches in that area, all other hardware was placed in the overlap area where the deck seems very strong. i might have to go with 3/8 divivycell. do you think the heat from the epoxy kikking off might damage the primer or paint? thanks for all your help. i might be abel to get some kladgucel localy is this the same type product.

Reread and understand my previous post.

i think i might use my left over west system epoxy thickend with 404

high density filler.

Use it for fairing compound, it is not laminating resin.

im not sure ill have to measure but 3/4 will probably be to thick

because of the amount of space between the headliner and deck plus i

have to fit bolts in the area.

You need to allow 1" of gap between deck glass and head liner to cover
the foam + the glass on both sides of the foam.

I won't bore you with moment of inertia calculations but the stiffness
of a member varies as the cube of the thickness.

Thickness is good.

If that is a problem, **** can the head liner and fair out the foam and
glass to look right in this area.

Forget it, see above.

do you think the heat from the epoxy kikking off might damage

the primer or paint?

Not if you do it my way.

i might be abel to get some kladgucel

Do you mean Klegcell?

localy is this the same type product.

If so, yes.
