ReefCrest AquaWELD?!

[GoFish]

Haven't picked any up yet, but have a couple ideas for toning down the white. Either by kneading in some charcoal powder or extra coralline algae? There may be a reef safe dye out there...
And if using it to secure a frag to your rockwork, maybe the "sammich" technique (dab of crazy glue, ball of aquaweld, dab of crazy glue?) just be quick about it and should set up quick and conform quite nicely. As far as building rockscape it looks like it does a solid job of that. Looking forward to trying it out, and may be useful for other stuff around the house too
