After fairing?

I'm winding down on my fairing, just waiting for my last shipment of micro-balloons, I underestimated my first order. I have two questions; 1) should I roll a coat of epoxy over the whole hull before I paint? 2) If I plan on only using thickened epoxy to hold the keel and stringers on, (no screws), should I attach them after the coat of epoxy or before. I would assume after.

Thanks,
John

EVERYONE DOES THAT.

YES. B4 YOU PAINT, SAND WITH 100 GRIT LIGHTLY.

2) If I plan on only using thickened epoxy to hold the keel and stringers on, (no screws), should I attach them after the coat of epoxy or before.

BEFORE JOHN. YOU'LL HAVE LOTS OF SANDING TO DO AFTER YOU APPLY THE KEELSONS... ASSUMING YOU WANT A GREAT FINISH. THERE IS A LOT OF EPOXY THAT IS APPLIED AS SMALL FILLETS (NO TAPE) ALONG THE EDGE OF THE KEELSON = WHERE THEY MEET THE HULL. A ROLLED UP 80 GRIT PIECE OF SANDPAPER IS A GREAT TOOL TO USE ON THE SMALL FILLETS TO FILL IN THE CRACKS CREATED WHERE THE KEELSONS MEET THE HULL. ASSUME YOUR KEELSONS ARE SAY... 1 3/4" WIDE... IF YOU SIT THEM ON TOP OF THE HULL, YOU'LL NOTE THAT THERE IS A LOT OF DAYLIGHT UNDER THOSE KEELSONS BECAUSE YOUR HULL FALLS AWAY ON EITHER SIDE... UNLESS YOU BEVEL THE KEELSON, BUT THAT'S A REALLY FUSSY WAY TO GO.

APPLY A GOOD COAT OF EPOXY OVER THE WHOLE PROGRAM ONCE DONE, DO THE 100 GRIT THING AND YOU'RE READY TO PAINT.

I would assume after.

Thanks,
John
 
Oh, it should be mentioned to all new boat builders, a finger tip wetted with denatured alcohol will smooth a small fillit better and easier than any sanding. I've thought about using a wetted tennis ball to smooth the larger fillits, but mine were already done so I didn't get to try it. Just be sure to do this when the epoxy has hardened some, but is still soft (kinda like clay).
 
Kenmacks tip is great. you can use rubber gloves and wet them. If for any reason you have to thin epoxy you can thin it with alcohol before you mix the hardener and epoxy together. Each part will look milky.Mix together and apply. You will have a thinned epoxy. The alcohol will evaporate as the epoxy cures. This is a trick I learned where you only need a thin coat. saves on sanding.
