glassing with epoxy for the first time. I have a layer of 1708 biax wetted out and am pretty happy with it, but need to add a few layers. problem is, my bottle of hardner fell and spilled so it's been a few days between the first layer being totally cured and when I'll be able to add my next layers.

I have previously done a lot of poly resin fiberglass work and know you need to sand/scuff between applications if more than 24hrs/ or you get a glossed over finish... does the same hold true with epoxy?

Thanks

Depends on if the epoxy your are using produces amine blush when it cures. Basically if it does clean off the blush... if it is blush free,, then laminate away.

The Gougeon Brothers have led the industry in epoxy development.

They build wooden planes with epoxy that last forever with proper care. Pretty strong at 10,000 feet.

Am sure when Scott sees this he'll be happy to make it a sticky here on the Rebuild Forum.

Great suggestion and thanks sHa_clap2

just need to add a layer along the corners to re-enforce them, and do a little clean-up on the inside edge where the hatch goes and it should be good.

(the blue you can see is from the lines I made to make sure I had the glass lined up correctly.)

planning cut the hole for the anchor to pass thru and add a layer of starboard for the anchor shanks to ride on.

Yea typically ill "liability sand" that before more glass. Takes all the burrs and whatnot down smooth. Liability sanding is what you do so you dont run glass splinters into yourself working on the boat (and so youre nice to the people working on it after you).

Did this with the drill press and a holesaw the other day spoop_smileypoophitsthefan_100-1001

ouch! is that through both fingers? cripes.

did an acetone scrub, then scuffed it with 60 grit, then acetone, then laid the next layer on. solid as a rock now. need to do just a little sanding on the lip where the hinges will go and then it will be ready to install.

definitely like working with epoxy better than polyester (aside from the price),,, but the pump system makes mixing a no-brainer and everything goes much faster it seems.

Might want to think of putting in a small box area in it to keep dock lines separate from the anchor line. Will make it fast and easy to grab it when docking.
