any idea, would you recommend it ??

Forget you heard about it...............


basically it is not a bad formulation, but unstable. (I mean it does not provide the same properties in each supply)

The original poster must *definitely* do as Ilan Voyager says a couple posts back. If you have used epoxy as a fastener anywhere, but leave the wood open to the elements, the wood will breathe (ie: expand and contract with varying moisture and temperature). As the wood changes shape and size, it will break free of the epoxy, if left untreated.

You can sheath the outside with glass/epoxy for durability, but you MUST put 3 coats of epoxy on the inside of the hull, absolutely encapsulating all wood so that you can be sure it doesn't breathe and go to work loosening the existing epoxy joints you show in the photos.

Would you guys rercommend I mix anything such as West Microfiber to the resin when applying the inner side of the boat ??

I wouldn't suggest you mix anything with the epoxy. Just roller it on, 3 layers of it. You aren't applying it for strength in there, just to keep the moisture level of the wood stable. That's its only purpose.

Abrasion ??? From whom ?? When you expoy both sides the wood bewteen epoxy start faster rot. In stripe planking method stripes inside the both you must paint using breathable varnish, 5-6 layers.

What comment are you referring to about abrasion, wolnym, and haven't you heard that epoxy inside and out is exactly how normal modern strip-builds are done? Varnish is a very high maintainance coating compared to epoxy.
You may be more familiar with the older type of edge-fastened strip construction.

Alan,
modern and wooden for me it's not the same. Maybe I'm not perfect in English but epoxy for me means using cold molded method on polished wood. Put the epoxy resin with mat glass on both sides of the boat it's not a good idea.
p.s.
If I something missunderstood, I'm sorry.

No problem. I think you may misunderstand, but not speaking English well, it's still good to see you posting. I am not sure what you read that you don't agree with. Which post?

Well it is in fact a very good idea when the design was done accordingly.
