If the ez fillet is not completely cured you can go ahead and glass and epoxy over it. If it has completely cured clean it with water to remove any blush lightly sand it, and then proceed with epoxy and glass.

I've used ez fillet and have found the epoxy component blushes. Blush needs to be removed before additional epoxy is added. Blush is water soluble, there is no need to use a solvent.

When epoxy/glossing the bottom, if you use System Three silvertip laminating resin you have something like 72 hour to recoat without sanding, and silver tip is non-blushing.

If this is an old bottom with irregularities consider fairing with quickfair before glassing. Glass won't conform to digs and other irregularities. Also consider coating the entire bottom with epoxy, let it cure and then lightly sand, and then proceed to glassing and filling the weave. That coating schedule provides less opportunity for starving the glass/plywood interface of epoxy.

Check out the System Three epoxy manual.

I agree with Eric,the old plywood will be like a sponge.Coat first with neat epoxy let cure to seal the bottom then wipe,sand and glass.

Thanks Eric,

I wound up waiting until the next day to glass the bottom ..... I am doing this outside and it started to get dark and it came out great.

I gave it a coat of epoxy on the bare wood , fillet, and 2 layers of 6 oz glass so far.... I had already put 18 oz, glass on the inside floor ..... now I am wondering if  12oz on the outside and 18.5 on the inside is enough structurally for a decked dory or if I need to do another 6oz layer on the outside bottom ?

I wanted to seal the bottom so I can put the boat in the water and find level so I can slope the decking to footwells for drainage and determine oarlock placement , I feel the oarlocks are located a little to far back of the center of the boat right now
