    As some of you know, I'm building a Nova Scotia Dory...and the construction is White oak frames and planked with cypress...I have a few imperfections in the build that will take some filler...I have tried using West 105 mixed with sawdust from the planks...it works to some degree, but leave some pin holes in the seams...so, I'm think about using a white marine tex type product to fill some of the holes and seams???? any input will be helpful !:idea:

    Marine Tex is much harder than cypress and will make it hard to sand and fair. I assume you mean 405 filler. It can be made to flow better by adding some 406 (colloidal silica) to it. Put the least possible or it will be hard to sand.

    405 is a West System product and is phenol spheres with some wood flour tossed in for color and a splash of silica for viscosity control and stiffness.

    Try System Three's "Quick fair" premixed filler. It dries quickly, sands easily and is non-sagging out of the container. It's more costly to buy pre-mix formulas, but a lot easier than mixing your own, if you're a novice or doing small jobs.

    Purchase online, save local sales tax and it'll be at your door in a few days.

    Quick Fair is a simple 2:1 mix and pretty hard to screw up. It needs to be thoroughly mixed, but the color change makes this fairly easy. It's hand sandable in a few hours and machine sandable in a couple more.

    So you said you used sawdust from the planks - right?

    You can get by with dust from a sander, but saw dust is too coarse, especially if you load it too much.

    West 405 is an entirely different thing. Works easily, reasonably cheap.
    No need to go with some premixed expensive stuff.

    To each his own.
