Marinetex is not ideal for fairing a keel...

Just wanted to let you know that if, like me, you used a colloidal silica/epoxy mix the last time you faired your keel only to spend 6 gazillion hours sanding it down - and if, like me, you were thinking that this time you might want to try fairing your keel with something that doesn't take the entire sailing season to smooth out... Don't choose Marinetex !

It's great stuff - hard as a rock - bonds wonderfully to lead (and cradles). If the engine block for my diesel somehow fell out of the boat I am sure I could fashion a new, perfectly serviceable one out of Marinetex. But gosh, golly, gee whiz, darn it all - it sure takes a long time to sand this stuff away !

LOL, yes, sanding collodial silica thickened epoxy is about as fast as sanding rock. That's why West Systems doesn't recommend collodial silica for fairing situations.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

I like marinetex for drill and fill aplications such as stanchion bolt holes and such as the compressive strength is quite high.

Almost done now - 9 hours - figure another 2 to finish. No good reason to do it to this degree as we're not racing, but if I don't I'll just sit and stew about it every time someone sails past us ( not that we expect that to happen often of course ).

Microballoon Mix

For fairing use the West epoxy and 410 Microlight filler. Mix a paste to desired thickness and spread - very easy to sand. The collodial silica mix hardens like rock...

Well, if you consider that collodial silica is basically very fine sand... you can understand why sanding it is so difficult.

Marinetek is wonderful stuff. You just want to spread it very smooth, very very close to the final shape.

And it comes in two colours.

White is better for fiberglass, etc. The grey is better for industrial (metal) machinery-related uses.
