Here is a quick question regarding epoxy coating the exterior of the side panels.
Before applying the first coat of epoxy to the side panels, how much sanding do you guys do? I mean should I be looking to get these panels really smooth before putting on the first coat? Or do you coat it once and worry about getting it all smoothed out after the fact?

My plan is to put on the first coat, build the boat, then apply the second coat - followed by varnish (on the exterior).

If I am going to oil the interior, do I need to epoxy anything on the interior before applying the oil?

These are probably big time newbie questions, but what can I say...

Thanks!
Jason

No sanding is fine. The first coat is to soak in and bind the top layer of the plywood. The only thing to look for is a ding or scratch that should me tapped back into place and given a couple of scrubs with 80 grit to smooth out. Also look for any pencil marks and make sure to give them a light sand with 80 grit.
Jason,

Welcome to your first project. I did a boat with epoxy exterior then varnish. I did not sand at all, I went straight to the Epoxy. It was "A" grade plywood- so it was very smooth, and I took care of it around the shop, to not marr it up. After the first coat, I sanded with a random orbit, then did another coat. The first coat basically clogs the wood pores, and stiffens it all up. any subsequent coats are truly on the surface. You can sand that smooth get it real nice. On goes the varnish. I did all this work with the panels flat, before the boat was built.

DO NOT EPOXY the interior if you plan to oil. The oil penetrates the wood, but if you epoxy it, nothing penetrates.

Good luck!
Thanks for the info guys.
I am really hoping to get started on this phase of the project soon...
We got some snow this weekend so I was tied up dealing with that.
Maybe this coming weekend.

I was thinking, what kind of wood? if it is fir, do not sand it- fir tends to get "ridges" when it is sanded- this is because the hard and soft fibers will sand differently. Your best to epoxy it, get a coat onit, then sand it, but not through the epoxy.

the exotics dont have this problem.
I am using meranti hydrotek
As in any sealer, such as Benite, the purpose is to raise the grain and stabilize the substrate. The same can be said of epoxy sealers. Don't worry too much about the existing plywood surface except for damage, seal the wood and then begin the sanding process. IMHO
