I needed west systems 403 microfibers, what I got was the micro balloon fairing filler. The boatyard doesnt have 403, geesh now he tells me. Going through west marine will take a week and a half.
If anyone can beat this time for me, how about 20 oz? Shipped to Japan paid by me + the 20 oz.
There are plenty of places in the US that will ship to Japan. You might try Fiberglass Supply or Jamestown Distributors to start. Also, 403 is just finely cut up cloth, lots of companies have their own version that is more or less the same. You may ask another boatyard or marine supplier if they have their own.
If you are still in a pinch you can make it yourself by cutting 6 oz or so cloth along the warp path 1cm wide and then doing the same along the fill. If you need it finer then that, go to .5cm or .25. Gather the stuff in a container and stir it around really well so the strands come apart. Wear a mask for sure! That will hold you over for 1.5 weeks.
