Well, I have to say to all people that still wonder whether they should give blu-stuff a try to not think twice. If I say that it improved by 100% the quality and speed of my conversions, it would still be an understatement. If you are into the hobby, you NEED to try this material.For me the highlights are the curing time, the fact that the putty is rigid but still flexible enough, its smooth finish and its incredible to capacity to hold sharp details.A must for every converter/hobbyist.
