It sounds like you are wanting to just coat the boat with resin and forget the fiberglass. Your first coat of resin has soaked into the wood, good thing but has laft some grain exposed. You will need to apply a few more coats of resin to fill the grain in, sanding lightly between coats to knock down the high spots. Thats if you let it cure fully between coats. If you let the resin just get tacky, then you can apply another coat without sanding. I prefer this method if time is available, it speeds up the whole process tremendously. After you have enough coats of cured resin then you can sand it down to a smooth finish.

When you are happy with the results then wipe the hull down with some degreaser using white paper towels. Now you are ready for a coat of primer. Your final finish is only as good as the effort you put into it.

Epoxy resins are also used to produce fiberglass products.
They are completely different than the hobby epoxies used for cement.

Here is a tutorial on epoxy resing and fiberglass.

Welcome Watertight! I would highly reccomend using fiberglass on the Dauntless. With all the planking the fiberglass gives quite a bit of strength. The fiberglass will give the boat a great smooth finish for paint.

With all the planking in the bow if the boat ever hit or bumped something like a rock or a piece of wood you would be quickly taking on water. Dumas wood, paint and resin are a bad mix for a boat that will see water if thats what you intend to do. The resin alone can become brittle.

Have any pictures?

watertight, welcome to RC groups matey

once you have used resin on the outside, add fibreglass resin on the inside to treat the insides, as unlike abs plastic, wood can swell up if ya boat takes on water. NOT GOOD!

but hope to see ya on the water soon.

watertight, If you only use polyester resins to seal the hull, you run a great risk of it cracking or even pealing in a short period of time. When ever you use a poly resin your best to use it with cloth to help stengthen the hull and prevent water from ruing your efforts. Epoxy coatings do not always need cloth to give a good protective coating on your prodject. The best thing to do is to always coat thye inside of the hull and the outside. As with the others, sand the surfaces and make sure every thing has had sufficiant time to cure as your location (climate) has an effect on the cure time!

Flat paint will cover the most blemishes. Next is a matte finish followed by a glossy. The glossy has a tendency to make models look like toys. That being said, many times a gloss can be used on a hull and a matte or flat finish can be used on the deck. It just depends on the type of boat you are building and how you want it to look.
