I have recently used a black kit on my a pillars. the result is pretty good tbh but up against a flocked a pillar that someone has had done professionally you do notice a difference. I have just done my dash as well but it hasn't really turned out to well, if you don't use enough adhesive it will turn out patchy (really not a good look) but you do get a huge amount of flock in the bag you get but it does take practice.
The a pillars i have done have turned out quite good, ill try upload pics next time im on.
