Easy to use, try to keep your work area out of the wind.
I uses this to fix some damage to the rudder on my sailboat, mixed with polyester resin until it was a thick paste and applied it with a wide popsicle stick and sanded it down. Worked perfectly! And yes I know that polyester is not the best choice below the waterline but it just the rudder and its what I had on hand, it will be just fine.

Works very well, and not as messy as I feared.
Works very well, and not as messy as I feared. It's not exactly powder or dust -- it's hard to describe; maybe kinda like fake snow. Do handle with care, but it not too bad. Good value; one bag will go pretty far. Be aware that it will noticeably lighten the color of your epoxy if you add a substantial amount.

Does not dissolve clear
Do not get this expecting it to turn up clear after mixing. It's kinda a pita to mix too. It does work well with pigments
